Abstract:
1. A method of fabricating a solar cell on a base comprising; electrodepositing a Group IIB-VIA material containing sub-layer over the base at a temperature below 100° C.; and forming a second layer comprising a second Group IIB-VIA substance on the sub-layer, wherein: the sub-layer and the second layer together constitute a composite layer; the Group IIB-VIA material containing sub-layer comprises Te and at least one of Cd, Zn, Mn and Mg, and further comprises a p-type dopant selected from the group consisting of Cu, Sb, As and P; the second Group IIB-VIA substance comprises CdTe; and the step of forming the second layer is carried out at or above a temperature of 200° C. so that the p-type dopant diffuses from the Group IIB-VIA material containing sub-layer into the second layer thus yielding a doped composite layer.
