Quantum dot-sensitized solar cells (QDSCs) are promising devices for solar energy conversion, because of their specific optical and electronic properties, such as high molar extinction coefficient, size-dependent absorption spectrum, and multiple exciton generation effects. However, the photovoltaic performance of QDSCs is still lower than its molecular sensitizer counterpart, dye-sensitized solar cells (DSCs), let alone the recent developed perovskite solar cells. In order to enhance the power conversion efficiency, one of the essential ways is to improve the fill factor by modifying counter electrodes. Herein I review the recent advances in the field of counter electrode materials and discuss future prospects for quantum dot-sensitized solar cells.
