Benchmark solar to hydrogen conversion efficiency of 18.7% was achieved via photovoltaic cell–electrolyzer system without using well-known expensive III-V-based light absorber. Comparison with previous studies indicates that this efficiency bench is impressive for using less junction (2jn instead of 3∼4jn for III/V), relatively cheap perovskite and silicone solar cell, and high solar electricity to chemical efficiency (74.2%).

钙钛矿Tandems促进了太阳能制氢

通过光伏电池-电解器系统，无需使用众所周知的昂贵的基于III-V的光吸收剂，即可将基准太阳能转化为氢气的效率达到18.7％。与先前研究的比较表明，该效率基准令人印象深刻，因为它使用的结较少（III / V为2jn而不是3〜4jn），钙钛矿和有机硅太阳能电池价格相对便宜，太阳能对化学的效率较高（74.2％）。
