Abstract
A multilayer structure to form absorber layers for solar cells. The multilayer structure includes a base comprising a contact layer on a substrate layer, a first layer on the contact layer, and a metallic layer on the first layer. The first layer includes an indium-gallium-selenide film and the gallium to indium molar ratio of the indium-gallium-selenide film is in the range of 0 to 0.8. The metallic layer includes gallium and indium without selenium. Additional selenium is deposited onto the metallic layer before annealing the structure for forming an absorber.
