Abstract
A method for fabricating a shaped thin-film photovoltaic device. The method includes providing a shaped substrate member including a surface region and forming a first electrode layer overlying the surface region. Additionally, the method includes forming an absorber comprising copper species, indium species, and selenide species overlying the first electrode layer. The method further includes scribing through the absorber using a mechanical tip to form a first pattern. Furthermore, the method includes forming a window layer comprising cadmium sulfide species overlying the absorber including the first pattern. Moreover, the method includes scribing through the window layer and the absorber using the mechanical tip to form a second pattern. The second pattern is separated a distance from the first pattern.
