摘要：
A method for producing a powder of a Cu(In,GA)Se2 compound, including the following steps: Cu and In and/or Cu and Ga are alloyed to form a CuIn and/or CuGa alloy with a substoichiometric content of Cu; producing a powder of the CuIn and/or CuG alloy; Se and either KI or NaI are added to the powder, the mixture is heated until a melted mass is formed, in which the Cu(In,Ga)Se2 compound recrystallizes, and the powder grains to be produced simultaneously grow; and the melted mass is cooled in order to interrupt the growth of the grains. The invention also relates to a monogram membrane solar cell containing a back contact, a monogram membrane containing a powder produced by the inventive method, at least one semiconductor layer, and a front contact.
摘要（中）：
制备Cu（In，GA）Se 2+化合物的粉末的方法，包括以下步骤：将Cu和In和/或Cu和Ga合金化以形成CuIn和/或CuGa合金 具有亚化学计量的Cu含量; 生成CuIn和/或CuG合金的粉末; 将Se和KI或NaI加入到粉末中，将混合物加热直到形成熔融物质，其中Cu（In，Ga）Se 2重复化，粉末颗粒为 同时生长; 并且熔化的质量被冷却以便中断晶粒的生长。 本发明还涉及一种含有背接触的记号膜太阳能电池，含有本发明方法制造的粉末的单字膜，至少一个半导体层和前触点。
