Se InGaSe/Cu CIGS Fabrication of CIGS thin film from Se-deficient stacked InGaSe/Cu precursors

摘要

The present invention relates to a CIGS thin film manufacturing method and a solar cell including the CIGS thin film which is a light absorbing layer of the solar cell thus manufactured. The present invention solves the problem of adsorption to the substrate caused by the selenization process by growing the CIGS thin film without supplying the external Se by using the (In, Ga) Se / Cu laminate precursor structure containing Se, , And by applying this process, a large-area thin film solar cell having excellent reproducibility can be manufactured.
