Abstract
A thin-film solar cell () is provided. The thin-film solar cell () comprises a flexible metallic substrate () having a first surface and a second surface. A back metal contact layer () is deposited on the first surface of the flexible metallic substrate (). A semiconductor absorber layer () is deposited on the back metal contact. A photoactive film deposited on the semiconductor absorber layer () forms a heterojunction structure and a grid contact () deposited on the heterjunction structure. The flexible metal substrate () can be constructed of either aluminium or stainless steel. Furthermore, a method of constructing a solar cell is provided. The method comprises providing an aluminum substrate (), depositing a semiconductor absorber layer () on the aluminum substrate (), and insulating the aluminum substrate () from the semiconductor absorber layer () to inhibit reaction between the aluminum substrate () and the semiconductor absorber layer ().
