The role of metal deposits (e.g., Co and Pt) on p-InP photocathodes in the photoevolution of hydrogen from alkaline solutions was studied. The deposition of Co or Pt on a p-InP photocathode was found to increase the solar-to-chemical efficiency by more than an order of magnitude. Photocurrent-voltage curves before and after metal deposition have shown that the open-circuit voltage remains nearly constant at 0.65–0.77 V. Under a reverse bias of 0.1–0.6 V the presence of metal islands has a large effect on cell performance by improving the short-circuit current and fill factor. This indicates that the deposited metals act as classical catalysts on photocathodes in alkaline hydrogen generating photoelectrochemical cells.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
