Impact of Light-Induced Degradation on the Performance of Multijunction Thin-Film Silicon-Based Photoelectrochemical Water-Splitting Devices.

ABSTRACT: The impact of light-induced degradation (LID) of silicon photoelectrodes on the solar-to-hydrogen efficiency of photoelectrochemical (PEC) devices is investigated. To evaluate the effect, stabilized state-of-the-art thin-film silicon solar cells (after 1000 h of light soaking) were used as photocathodes in photovoltaic-electrochemical (PV-EC) device assemblies and their performances were compared to the performances of the initial solar-cell-based PV-EC devices. A wide range of photoelectrode configurations (tandem, triple, quadruple) was addressed. With regard to the widespread use of multijunction-based photoelectrodes in the literature, the results presented herein will have a high impact and may serve as guidelines for the design of photovoltaic devices particularly tailored for PEC ap
