APPARATUS AND METHOD FOR IMPROVING EFFICIENCY OF THIN-FILM PHOTOVOLTAIC DEVICES

摘要

A method for producing, apparatus for producing and photovoltaic device including semiconductor layers with halide heat treated surfaces that increase grain growth within at least of the semiconductor layers and improve the interface between the semiconductor layers. The halide heat treatment includes applying and heating multiple coatings of a halide compound on surfaces adjacent to or part of the semiconductor layers.
