Abstract
Use of nanostructures in photoelectrochemical solar cells has potential to provide high conversion efficiency. Films of CdSe nanocrystals of different size have been prepared on titanium substrate by pulsed electrodeposition. These are used as photoelectrode in photelectrochemical cells and photovoltaic effect is studied. It is observed that photoelectrodes prepared with 1:1 duty cycle give best performance. Increase in open circuit voltage and short circuit current with the incident light intensity is observed to be logarithmic and linear respectively.
