Recent Advances in Optimization of Photoanodes and Counter Electrodes of Dye-Sensitized Solar Cells

Abstract

Since 1991, dye-sensitized solar cells (DSSCs) have emerged as a potential alternative to conventional silicon photovoltaics for conversion of solar energy to electric power, due to their advantages of costeffectiveness, sustainability and ease of fabrication among others. As the functioning of DSSCs depends on the sum of the functions of individual components, effective understanding and optimization of these components is important for the optimization of the device itself. Therefore, this review focuses on the recent developments made in the fabrication of two particular components of DSSCs, viz. photoanode and counter electrode.

Self-Assembly Synthesis of the MoS2/PtCo Alloy Counter Electrodes for High-Efficiency and Stable Low-Cost Dye-Sensitized Solar Cells

“…The high potential peak which can be ascribed to the Reaction (1). Moreover, the low potential peak which is mainly related to performance of DSSCs is attributed to the Reaction (2) [ 80 ]. 2I 3 − ↔ 3I 2 + 2e − 3I − ↔ I 3 − + 2e − …”

“…The high potential peak which can be ascribed to the Reaction (1). Moreover, the low potential peak which is mainly related to performance of DSSCs is attributed to the Reaction (2) [80]. During the process of preparing CEs with doctor blade method, we found that with 5 wt% PtCo and 12 wt% PtCo, surface tension of liquid is large and not easy to spread, so it cannot be wetted and converged on conductive glass.…”
