研究目的
Investigating the function of photoanode in dye-sensitized solar cells (DSSCs), focusing on charge transfer dynamics, challenges, and alternative strategies to improve efficiency.
研究成果
The performance of DSSCs is determined by the photoanode, dye sensitizer, and their interfaces. Strategies to improve efficiency include TiCl4 treatment, use of composites, light scattering, nanoarchitectures, doping, and interfacial engineering. Dye aggregation and charge recombination are major challenges that need to be addressed.
