Abstract
A method of manufacturing partially light transparent thin film solar cells generally includes forming a solar cell structure stack and forming multiple openings through the solar cell structure stack. The solar cell structure stack includes a flexible foil substrate, a contact layer formed over the flexible foil substrate, a Group IBIIIAVIA absorber layer formed over the contact layer and a transparent conductive layer formed over the Group IBIIIAVIA absorber layer. A terminal structure including at least one busbar and a plurality of conductive finger patterns is deposited onto a top surface of the transparent conductive layer forming a semi-transparent solar cell.
