Abstract Antimony selenide (Sb2Se3) is a promising absorber material for thin film photovoltaics because of its attractive material, optical and electrical properties. In recent years, the power conversion efficiency (PCE) of Sb2Se3 thin film solar cells has gradually enhanced to 5.6%. In this article, we systematically studied the basic physical properties of Sb2Se3 such as dielectric constant, anisotropic mobility, carrier lifetime, diffusion length, defect depth, defect density and optical band tail states. We believe such a comprehensive characterization of the basic physical properties of Sb2Se3 lays a solid foundation for further optimization of solar device performance.

2. 使用改进的PCBM和PEDOT:PSS材料制造有机热电模块

Fabricate organic thermoelectric modules use modified PCBM and PEDOT: PSS materials 

Feng GAO, Yuchun LIU, Yan XIONG, Ping WU, Bin HU, Ling XU

Front. Optoelectron.    2017, 10 (2): 117-123.   

Abstract In this paper, we fabricated an organic thermoelectric (TE) device with modified [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS); the device showed good stability in air condition. For n-leg, PCBM were doped with acridine orange base (3,6-bis(dimethylamino)acridine) (AOB) and 1,3-dimethyl-2,3-dihydro-1H-benzoimidazole (N-DMBI). Co-doped PCBM utilizes synergistic effects of AOB and N-DMBI, resulting in excellent electrical conductivity and Seebeck coefficient values reaching 2 S/cm and -500 mV/K, respectively, at room temperature with dopant molar ratio of 0.11. P-type leg used modified PEDOT:PSS. Based on modified PCBM and PEDOT:PSS materials, we fabricated a TE module device with 48 p-type and n-type thermocouple and tested their output voltage, short current, and power. Output voltage measured ~0.82 V, and generated power reached almost 945 mW with 75 K temperature gradient at 453 K hot-side temperature. These promising results showed potential of modified PEDOT and PCBM as TE materials for application in device optimization.

3. 用于超宽带光子应用的铋/铒共掺光纤的发展

Development of Bi/Er co-doped optical fibers for ultra-broadband photonic applications 

Yanhua LUO, Binbin YAN, Jianzhong ZHANG, Jianxiang WEN, Jun HE, Gang-Ding PENG

Front. Optoelectron.    2018, 11 (1): 37-52.  

Abstract Targeting the huge unused bandwidth (BW) of modern telecommunication networks, Bi/Er co-doped silica optical fibers (BEDFs) have been proposed and developed for ultra-broadband, high-gain optical amplifiers covering the 1150–1700 nm wavelength range. Ultra-broadband luminescence has been demonstrated in both BEDFs and bismuth/erbium/ytterbium co-doped optical fibers (BEYDFs) fabricated with the modified chemical vapor deposition (MCVD) and in situ doping techniques. Several novel and sophisticated techniques have been developed for the fabrication and characterization of the new active fibers. For controlling the performance of the active fibers, post-treatment processes using high temperature, g-radiation, and laser light have been introduced. Although many fundamental scientific and technological issues and challenges still remain, several photonic applications, such as fiber sensing, fiber gratings, fiber amplification, fiber lasers, etc., have already been demonstrated.

4. 光谱域光学相干层析成像中介质色散的计算和校正

Front. Optoelectron.    2017, 10 (3): 323-328.   

Abstract A method for determining and correcting distortions in spectral-domain optical coherence tomography images caused by medium dispersion was developed. The method is based on analysis of the phase distribution of the interference signal recorded by an optical coherence tomography device using an iterative approach to find and compensate for the effect of a medium’s chromatic dispersion on point-spread function broadening in optical coherence tomography. This enables compensation of the impact of medium dispersion to an accuracy of a fraction of a radian (units of percent) while avoiding additional measurements and solution of the optimization problem. The robustness of the method was demonstrated experimentally using model and biological objects.

Mark H. BERGEN, Ferdinand S. SCHAAL, Richard KLUKAS, Julian CHENG, Jonathan F. HOLZMAN

Front. Optoelectron.    2018, 11 (2): 116-127.   

Abstract There is an emerging market today for indoor positioning systems capable of working alongside global navigation satellite systems, such as the global positioning system, in indoor environments. Many systems have been proposed in the literature but all of them have fundamental flaws that hold them back from widescale implementation. We review angle-of-arrival (AOA) and angle-difference-of-arrival (ADOA) optical indoor positioning systems which have been proven to be robust, accurate, and easily implementable. We build an AOA/ADOA optical indoor positioning system out of a simple commercial high-speed camera and white light light emitting diodes (LEDs) which operate over a working area of 1 m3, and compare its performance to other indoor positioning methods. The AOA and ADOA systems achieve positioning with low errors of 1.2 and 3.7 cm, respectively.

6. 用于医学放射治疗的光子剂量计的最新进展

Recent advances in photonic dosimeters for medical radiation therapy 

James ARCHER, Enbang LI

Front. Optoelectron.    2018, 11 (1): 23-29.   

Abstract Radiation therapy, which uses X-rays to destroy or injure cancer cells, has become one of the most important modalities to treat the primary cancer or advanced cancer. High resolution, water equivalent and passive X-ray dosimeters are highly desirable for developing quality assurance (QA) systems for novel cancer therapy like microbeam radiation therapy (MRT) which is currently under development. Here we present the latest developments of high spatial resolution scintillator based photonic dosimeters, and their applications to clinical external radiation beam therapies: specifically high energy linear accelerator (LINAC) photon beams and low energy synchrotron photon beams. We have developed optical fiber dosimeters with spatial resolutions ranging from 50 to 500 mm and tested them with LINAC beams and synchrotron microbeams. For LINAC beams, the fiber-optic probes were exposed to a 6 MV, 10 cm by 10 cm X-ray field and, the beam profiles as well as the depth dose profiles were measured at a source-to-surface distance (SSD) of 100 cm. We have also demonstrated the possibility for temporally separating Cherenkov light from the pulsed LINAC scintillation signals. Using the 50 mm fiber probes, we have successfully resolved the microstructures of the microbeams generated by the imaging and medical beamline (IMBL) at the Australian Synchrotron and measured the peak-to-valley dose ratios (PVDRs). In this paper, we summarize the results we have achieved so far, and discuss the possible solutions to the issues and challenges we have faced, also highlight the future work to further enhance the performances of the photonic dosimeters.

7. 容积式手持光声成像中声速变化的考量

Accounting for speed of sound variations in volumetric hand-held optoacoustic imaging 

X. Luís DEáN-BEN, Ali ÖZBEK, Daniel RAZANSKY

Front. Optoelectron.    2017, 10 (3): 280-286.   

Abstract Hand-held implementations of recently introduced real-time volumetric tomography approaches represent a promising path toward clinical translation of the optoacoustic technology. To this end, rapid acquisition of optoacoustic image data with spherical matrix arrays has attained exquisite visualizations of three-dimensional vascular morphology and function deep in human tissues. Nevertheless, significant reconstruction inaccuracies may arise from speed of sound (SoS) mismatches between the imaged tissue and the coupling medium used to propagate the generated optoacoustic responses toward the ultrasound sensing elements. Herein, we analyze the effects of SoS variations in three-dimensional hand-held tomographic acquisition geometries. An efficient graphics processing unit (GPU)-based reconstruction framework is further proposed to mitigate the SoS-related image quality degradation without compromising the high-frame-rate volumetric imaging performance of the method, essential for real-time visualization during hand-held scans.

8. 目前用于生物医学的声光层析成像方法的回顾

Review of current methods of acousto-optical tomography for biomedical applications 

Jacqueline GUNTHER, Stefan ANDERSSON-ENGELS

Front. Optoelectron.    2017, 10 (3): 211-238.   

Abstract The field of acousto-optical tomography (AOT) for medical applications began in the 1990s and has since developed multiple techniques for the detection of ultrasound-modulated light. Light becomes frequency shifted as it travels through an ultrasound beam. This “tagged” light can be detected and used for focused optical imaging. Here, we present a comprehensive overview of the techniques that have developed since around 2011 in the field of biomedical AOT. This includes how AOT has advanced by taken advantage of the research conducted in the ultrasound, as well as, the optical fields. Also, simulations and reconstruction algorithms have been formulated specifically for AOT imaging over this time period. Future progression of AOT relies on its ability to provide significant contributions to in vivoimaging for biomedical applications. We outline the challenges that AOT still faces to make in vivoimaging possible and what has been accomplished thus far, as well as possible future directions.

9. 宽带共形超材料吸收器

Broadband and conformal metamaterial absorber 

Xiangkun KONG, Junyi XU, Jin-jun MO, Shaobin LIU

Front. Optoelectron.    2017, 10 (2): 124-131.   

Abstract In this study, a new broadband and conformal metamaterial absorber using two flexible substrates was proposed. Simulation results showed that the proposed absorber exhibited an absorption band from 6.08 to 13.04 GHz and a high absorption of 90%, because it was planar. The absorber was broadband as its relative absorption bandwidth was 72.8%. Moreover, the proposed absorber was insensitive to the polarization of the TE and TM waves. The absorber was ultra-thin; its total thickness was only 0.07λ at the lowest operating frequency. Furthermore, different regions of absorption can be adjusted by lumping and loading two resistors onto the polyimide film, respectively. Moreover, compared with the conventional microwave absorber, the absorption bandwidth of the proposed absorber can be broadened and enhanced when it was bent and conformed to the surface of objects. Experimental and simulation results were in agreement. The proposed absorber is a promising absorbing element in scientific and technical applications because of its broadband absorption, polarization insensitivity, and flexible substrates.

10. 无空穴传输层的倒置平面混合铅-锡钙钛矿基太阳能电池

Hole-transporting layer-free inverted planar mixed lead-tin perovskite-based solar cells 

Yuqin LIAO, Xianyuan JIANG, Wenjia ZHOU, Zhifang SHI, Binghan LI, Qixi MI, Zhijun NING

Front. Optoelectron.    2017, 10 (2): 103-110.   

Abstract Mixed lead-tin (Pb-Sn) perovskites present a promising strategy to extend the light-harvesting range of perovskite-based solar cells (PSCs). The use of electron-transporting layer or hole-transporting layer (HTL) is critical to achieve high device efficiency. This strategy, however, requires tedious layer-by-layer fabrication as well as high-temperature annealing for certain oxides. In this work, we fabricated HTL-free planar FAPb0.5Sn0.5I3 PSCs with the highest efficiency of 7.94%. High short-circuit current density of 23.13 mA/cm2 was attained, indicating effective charge extraction at the ITO/FAPb0.5Sn0.5I3 interface. This finding provides an alternative strategy to simplify the manufacture of single-junction or tandem PSCs.

11. 用于双面a-Si:H/c-Si异质结太阳能电池的不同厚度的ZnO:B薄膜的结构、光学和电学性质

Structural, optical and electrical properties of ZnO: B thin films with different thickness for bifacial a-Si:H/c-Si heterojunction solar cells 

Dong XU, Sheng YIN, Xiangbin ZENG, Song YANG, Xixing WEN

Front. Optoelectron.    2017, 10 (1): 31-37.   

Abstract Textured surface boron-doped zinc oxide (BZO) thin films were fabricated by metal organic chemical vapor deposition as transparent conductive oxide (TCO) for solar cells. The surface microstructure was characterized by X-ray diffraction spectrum and scanning electron microscope. The optical transmittance was shown by optical transmittance microscope and the electrical properties were tested by Hall measurements. The thickness of the BZO film has crucial impact on the surface morphology, optical transmittance, and resistivity. The electrical and optical properties as well as surface microstructure varied inconsistently with the increase of the film thickness. The grain size and the surface roughness increased with the increase of the film thickness. The conductivity increased from 0.96×103 to 6.94×103 S/cm while the optical transmittance decreased from above 85% to nearly 80% with the increase of film thickness from 195 to 1021 nm. The BZO films deposited as both front and back transparent electrodes were applied to the bifacial p-type a-Si:H/i-type a-Si:H/n-type c-Si/i-type a-Si:H/n+-type a-Si:H heterojunction solar cells to obtain the optimized parameter of thickness. The highest efficiency of all the samples was 17.8% obtained with the BZO film thickness of 829 nm. Meanwhile, the fill factor was 0.676, the open-circuit voltage was 0.63 V and the short-circuit density was 41.79 mA/cm2. The properties of the solar cells changing with the thickness were also investigated.
