US Patent 6307148 -Compound semiconductor solar cell and production method thereof
Abstract
An indium layer and a copper layer, and whenever necessary, a gallium layer or a gallium-alloy layer, are laminated on an electrode film formed on one of the surfaces of a substrate to form a metallic film. The metallic film
is then subjected to sulfurization treatment or selenization treatment to form a p-type semiconductor layer made of ”CuInS2 or CuInSe2 ”
or ”Cu(In, Ga)S2 or Cu(In, Ga)Se2 ”. This p-type semiconductor layer is subjected to KCN treatment, for removing impurities such as
copper sulfide, copper selenide, etc., by a KCN solution, and an n-type semiconductor layer is formed on this p-type semiconductor layer to form a solar cell. In this instance, the indium layer is formed under heating, or is heat-treated by heat-treatment while the surface of the indium layer is exposed.
