研究目的
Investigating the accumulation of solar hydrogen in a photoelectrochemical system based on CdSe photoanode and MH cathode.
研究成果
The introduction of graphene oxide into CdSe films improves their characteristics by 25-30%. The composite cathode based on hydrogen-sorbing intermetallic alloys is compatible with the CdSe photoanode, and 95-98% of the current generated by sunlight at anodes is used for hydrogen accumulation on cathodes.
研究不足
The study is limited by the efficiency of the semiconductor photoanode and the specific conditions under which the experiments were conducted.
