Abstract: | Abstract The photovoltaic effect in Cu2s-CdS heterojunction has been the subject of study by a large number of investigators. Proper heat treatment of the junction plays crucial role in optimizing the performance of the heterojunction. In this paper, after a brief review of the work on Cu2S-CdS heterojunctions, the profile of copper in CdS as a function of heat treatment will be discussed. The diffusion of copper from Cu2S into CdS has been studied at various temperatures, by radioactive tracer methods. This has a bearing on the spectral response of the Cu2S-CdS cells as a function of heat treatment. |
