Photovoltaic cells with the structure of ZnO/CdS/CuInSe{sub 2} have been fabricated on single crystal CuInSe{sub 2} substrates obtained from p-type Bridgman-grown ingots. A chemical bath method was used to deposit the CdS film onto the abrasively-polished CuInSe{sub 2} substrates while r.f. sputtering was employed for the ZnO deposition. It was found that the performance of these cells were dominated by the high density of surface defects, which could be reduced by a substrate annealing prior to the CdS deposition. A conversion efficiency of 10.3% at about AM 1.5 under the sun has been achieved on ells with an effective area of 8 mm{sup 2}. Anti-reflection coating was not used in the present case.
