ABSTRACT:
A photo-voltaic hetero-junction is formed by chemical conversion of surface regions of a sheet of one conductivity type into material of a second conductivity type, the areas which are not to be converted being covered by a developed photo-resist layer which has previously been exposed to light through a mask. Electrical contacts are deposited on the regions of the second type and contacts to the material of the first type are formed by a layer deposited on a substrate under the sheet of material of the first type. This deposited layer of electrically-conductive material can also form the mask for initial exposure of the photo-resist layer.
