Abstract

Quantum dots (QDs) are the solution-processed semiconductors and have gained considerable attention recently. In this chapter, we review the recent progress in low-cost, efficient solar cells based on metal chalcogenide quantum dots (MCQDs). We focused particularly on different chemical synthesis method for QDs synthesis and fabrication. We tried the combination of CdSe QDs and single-crystal ZnO nanowires to demonstrate a new type of quantum-dot-sensitized solar cell which exhibits as high as 50-60% internal quantum efficiencies. In addition, we also review the sensitized-type solar cells, based on TiO2 inverse opal and the use of CdSe QDs as sensitizers which gives a power conversion efficiency of about 2.7%.
