Abstract:
1. A method of manufacturing an order vacancy compound (OVC), comprising: providing a trivalent ion, a hexavalent ion and one of a univalent ion and a bivalent ion for an electrodeposition process to form a solar energy absorbing film, wherein one of the univalent ion and the bivalent ion includes a copper cation, the trivalent ion includes an indium cation, and the hexavalent ion includes a selenium cation; and forming the OVC by performing an electrochemical etching process on the solar energy absorbing film for etching out the copper cation and the selenium cation, wherein the OVC is indium-rich, and a P-N homo junction is formed in the solar energy absorbing film.
