Chemically formed Cd1-xZnxSe photo-anodes: II. Preparation, electrical, photoelectrochemical and solar cell studies

For pt.I see ibid., p.729-32. Electrochemical photovoltaic cells, with open-circuit voltage=530 mV, short-circuit current=9 mA cm -2 , fill factor=0.55 and efficiency=5% have been fabricated from chemically formed Cd 1-x Zn x Se layers. The results of the measurements on donor concentration, minority carrier diffusion length, band bending and traps have also been reported. The performance of Cd 1-x Zn x Se-film-based solar cells has been compared with the CdSe-film-based cells and the possible reasons for the improved performance of the former cells have been discussed.
