Tailoring the electronic properties of one step electrodeposited CuInSe/sub 2/ films by annealing in Se vapor under controlled activity conditions. Elaboration of efficient CIS/ZnO solar cells

CuInSe alloys can be electrodeposited in a wide range of controlled composition. Annealing treatments under Se pressure transform these precursor films in large grained CuInSe/sub 2/ films with electronic properties suitable for solar cells, as shown by photoluminescence, resistivity, Hall effect, XRD and spectral responses measurements. The best CIS/CdS/ZnO cell yielded 6.5% efficiency.
