While photoelectrochemical (PEC) water splitting is a very promising route toward zero-carbon energy, conversion efficiency remains limited. Semiconductors with narrower band gaps can absorb much greater portion of the solar spectrum, thereby increasing efficiency. However, narrow gap (∼1 eV) III–V semiconductor photoelectrodes have not yet been thoroughly investigated. In this study, quaternary alloy InGaAsP demonstrated for first time to great potential PEC splitting, long-term goal...
Abstract An ideal catalytic interface for photoelectrodes that enables high efficiency and long‐term stability remains one of the keys to unlocking high‐performance solar water splitting.
