Abstract
Three photoelectrochemical devices, developed at Simon Fraser University, employing electrochemically deposited cadmium selenide photoanodes, a polysulphide redox electrolyte, and an in situ energy storage compartment were evaluated at DREO. A simulated solar source (AMI) was designed and built to evaluate these and other devices. Maximum power output of the devices was in the 10 to 20 mW range resulting in a solar (AMI) to electrical conversion efficiency of less than 1%. The efficiency was limited by counter electrode polarization, electrolyte light absorption and photocurrent losses originating in the semiconductor bulk or the depletion region. It is concluded that further research is required to characterize both the polycrystalline semiconductor phase and the semiconductor/electrolyte interface. An appreciation of the potential of photoelectrochemical devices is offered in the Conclusions and Recommendations section of the report.
