Investigations of a buffer layer grown on a CdTe surface

The possibilities for substitution of several contact pre-deposition proced ures by one technological step have been investigated with the aim of impro ving solar cell performance and reduction of the corresponding production c ost. Growth of a low-resistance buffer layer on the surface of a CdTe based solar cell is interesting not only from a:practical point of view but also concerning the structural and compositional changes introduced in the CdS- CdTe heterostructures. Information about the electrical properties of the l ayers involved is presented and discussed with respect to the further exten sion of this method.
