<p>PURPOSE: A method for manufacturing an inorganic thin film in order to manufacture a solar light absorbent layer is provided to form a copper indium gallium selenide(CIGS) based-thin film with a desire thickness for a solar light absorbent layer by adjusting a viscosity of a coating solution with an organic polymer which has a low decomposition temperature. CONSTITUTION: A copper chalcogenide, an indium chalcogenide, gallium and chalcogen element are melted in a hydrazine in order to prepare a reaction solution. Polycarbonate is mixed to the reaction solution in order to prepare a coating solution. The coating solution is applied on a base material to form a coating layer. The coating layer is thermally treated to form a CIGS based-thin film. A conductive layer(12), an absorbent layer(13) which is the CIGS based-thin film, a buffer layer(14) and a transparent window layer(15) are successively formed on a substrate(11).</p> |
