Thin film compound solar cell, thin film compound solar cell manufacturing method, thin film compound solar cell array, and thin film compound solar cell array manufacturing method

摘要

A solar cell stack composed of a plurality of compound semiconductor layers, a first electrode having a first polarity formed on a part of the first surface on the light receiving side of the solar cell stack, and a light receiving side of the solar cell stack A second electrode formed on a second surface different from the first surface and having a second polarity; and a second electrode having a second polarity formed on a part of the surface opposite to the light receiving side of the solar cell stack. A solar cell stack including a cell layer having a PN junction layer and a light receiving surface of the cell layer. The thin film compound solar cell is a thin film compound solar cell including a contact layer formed on a part of the surface on the side, and the third electrode is formed on the contact layer.
