Subjects: quantum dot; solar cell; quantum dotsensitized solar cell (QDSC); quantum confinement; multiple exciton generation (MEG); photoelectrode
Semiconductor quantum dots (QDs) have been drawing great attention recently as a material for solar energy conversion due to their versatile optical and electrical properties. The QD-sensitized solar cell (QDSC) is one of the burgeoning semiconductor QD solar cells that shows promising developments for the next generation of solar cells. This article focuses on recent developments in QDSCs, including 1) the effect of quantum confinement on QDSCs, 2) the multiple exciton generation (MEG) of QDs, 3) fabrication methods of QDs, and 4) nanocrystalline photoelectrodes for solar cells. We also make suggestions for future research on QDSCs. Although the efficiency of QDSCs is still low, we think there will be major breakthroughs in developing QDSCs in the future.Keywords: quantum dot; solar cell; quantum dotsensitized solar cell (QDSC); quantum confinement; multiple exciton generation (MEG); photoelectrode(Published: 31 October 2013)Citation: Nano Reviews 2013, 4: 22578 - http://dx.doi.org/10.3402/nano.v4i0.22578
