Summary: Third-generation solar cells, such as dye-sensitized solar cells and quantum dot-sensitized solar cells, require counter electrodes (CEs) for their functionality. Platinum-based CEs are dominant but expensive, thus alternative materials like transition metal chalcogenides (TMCs) and transition metal dichalcogenides (TMDs) have been explored. This study provides a comprehensive review of the major components and working principles of these solar cells, and evaluates the performance efficiencies resulting from TMS-based CEs compared to Pt-based CEs.

Summary: In this study, ATO/PbSe composite was designed as the counter electrode for QDSSCs, showing enhanced electrocatalytic activity and stability compared to PbSe CE obtained by PVD. The improved performance is attributed to the high specific surface area, permeability, conductivity, and interface connectivity of ATO/PbSe CE, providing more active sites for reduction and fast channels for ion diffusion and electron transport. As a result, the CdS QDSSCs and CdS/CdSe co-sensitized QDSSCs assembled with ATO/PbSe CE exhibited higher power conversion efficiency than PbSe CE obtained by PVD, with stable photovoltaic properties over 200 minutes.
