摘要

将用于析氢（HER）和尿素氧化（UOR）的过渡金属基催化剂层耦合到钙钛矿/硅（PK/Si）串联光伏（PV）电池上，并在模拟阳光下测试了富尿素碱性电解质制氢的性能。结果表明，UOR可以使光伏电池在太阳光照下的最大功率点运行，从而显著提高析氢性能，而在发生析氧反应（OER）时则没有这种效果。该组件在两天内保持稳定的性能。生成的高浓度NO2−证实了UOR过程中尿素过氧化途径的存在。

Solar H2 production by a perovskite/silicon tandem cell using urea oxidation†

Transition metal-based catalyst layers for hydrogen evolution (HER) and urea oxidation (UOR) are coupled to a perovskite/silicon (PK/Si) tandem photovoltaic (PV) cell and tested for H₂ production from urea-rich alkaline electrolytes under simulated sunlight. Results show that UOR significantly boosts H₂ evolution performance by allowing operation at the maximum power point of the PK/Si PV under solar illumination, which is not the case when the oxygen evolution reaction (OER) occurs. This assembly maintains stable performance over two days. The high concentration of produced NO₂⁻ confirms the occurrence of urea overoxidation pathways during UOR.
