Solar conversion efficiency is a primary parameter for evaluating the photocatalytic water splitting process and is an important metric that reflects the performance of a photocatalytic water splitting system. Incident Photon-to-Electron Conversion Efficiency (IPCE) is one of the four primary representations used in photocatalytic water splitting systems. It is employed to characterize the relationship between the material's photoelectrode reaction efficiency and light power, wavelength, and electrode potential. IPCE can be considered as an analytical diagnostic efficiency and can provide information about factors influencing the efficiency of the photoelectrode reaction.
