Recent development in colloidal quantum dots photovoltaics

Frontiers of Optoelectronics 2012, DOI 10.1007/s12200-012-0285-7.

Li Peng, Jiang Tang*, Mingqiang Zhu

摘要: The increasing demanding for sustainable and green energy supply spurred the surging research on high-
ef fi ciency, low-cost photovoltaics. Colloidal quantum dot solar cell (CQDSC) is a new type of photovoltaic device using lead chalcogenide quantum dot film as the absorber materials. It not only has the potential to break the 33 % Shockley-Queisser efficiency limit for single junction solar cell,  but  also  possesses  the  low-temperature,  high-throughput solution processing. Since its first report in 2005, CQDSCs experienced rapid progress achieving acertified 7% efficiency in 2012, an averaged 1% efficiency gain  per year.  In  this  paper,  we  reviewed  the research progress reported in the last two years. We started with background  introduction  and  motivation  for  CQDSC research. We then briefly introduced the evolution history of  CQDSC  development  as  well  as  multiple  exciton generation effect. We further focused on the latest efforts in improving  the  light  absorption  and  carrier  collection efficiency,  including  the  bulk-heterojunction  structure,
quantum  funnel  concept,  band  alignment  optimization and quantum dot passivation. Afterwards, we discussed the tandem solar cell and device stability, and concluded this article with a perspective. Hopefully, this review paper covers the major achievement in this field in year 2011 –2012  and  provides  readers  with  a  concise  and  clear understanding of recent CQDSC development.
