Abstract
A method for manufacturing a thin-film solar cell substrate of group IB, IIIB and VIB elements of the Periodic Table, by using an apparatus for depositing selenium (Se) on the thin-film solar cell substrate. The apparatus has a base with gas inlet and outlet pipes. A bell jar is placed on top of the base with an O-ring interposed between them. A thin-film solar cell precursor and Se powder are placed in a recess formed in a lower heating jig, and the lower heating jig is positioned on the base. An upper heating jig is placed on top of the lower heating jig. The upper heating jig is vertically moved by a vertically actuating mechanism. The upper and lower heating jigs are heated under vacuum so as to diffuse Se to the thin-film solar cells, whereby a CuInSe,alloy film is formed.
