Solar-driven water splitting powered by photovoltaics enables efficient storage of solar energy in the form of hydrogen fuel. In this work, we demonstrate efficient solar-to-hydrogen conversion using perovskite (PVK) tandem photovoltaics and a halogen-modulated metal–organic framework (MOF) electrocatalyst.
Using this electrocatalyst in a bias-free photovoltaic electrochemical (PV-EC) system with a PVK/organic tandem solar cell, we achieve 6.75% solar-to-hydrogen efficiency (η STH ). We also paired the electrocatalyst with a PVK photovoltaic module to drive water splitting at 206.7 mA with η STH of 10.17%.
