研究目的
Investigating the synthesis of PtSe alloys with different stoichiometric ratios on reduced graphene oxide (RGO) and their application as counter electrodes (CEs) for efficient third-generation solar cells.
研究成果
The synthesis of PtSe alloys on RGO using plasma technology results in efficient and durable CEs for DSCs, with the Pt0$74Se0.26/RGO electrode showing the highest efficiency due to its optimal catalytic activity and electrical conductivity.
研究不足
The study focuses on the synthesis and application of PtSe/RGO as CEs for DSCs, but the scalability and cost-effectiveness of the plasma technology for large-scale production are not addressed.
