Laser Spot Scanning of Photoelectrochemical Cells.
Abstract
Laser scanning of the photoelectrode in a photoelectrochemical cell is a powerful diagnostic tool for assessing the effect of surface modifications of the semiconductor electrode on cell performance. Photocurrent scan maps of photoelectrodes with external and/or white light bias allow the study of the effect of iR losses in the cell under operating conditions. A dye laser adds versatility to the system by permitting wavelength dependent responses to be mapped. The possibility of time resolved measurements, using a pulsed laser source, is also discussed.
