Project summary description:
This project aims to develop a novel, low cost and high performance monolithic photovoltaic electrochemical (PV-EC) device for clean hydrogen production. This device tailors and integrates low cost and high performance thin film and tandem photovoltaics achieving high solar to hydrogen conversion efficiency towards 20%.

Earth abundant and stable catalysts will be developed in this project to replace noble based catalysts, as well as novel architectures for electrical contacting, feed-through and catalyst integration in PV-EC devices. These innovations offer high performance and the potential for device costs 2 to 3 orders of magnitude lower than recent world record photoelectrochemical devices. While the original project plan is based on the development of water splitting for hydrogen production, new processes for hydrogen production other than water splitting has been developed and patented
