摘要：
An additional carbon layer between Cu(In,Ga)Se(2) (CIGS) layer and molybdenum (Mo) back contact can increase the efficiency of solar cells with very thin absorber layers. In this study the so produced solar cells co-evaporated on top of a carbon layer are compared with cells co-evaporated directly on molybdenum. We found that the carbon layer leads to higher maximum current densities and higher maximum open-circuit voltages and thus higher maximum efficiencies (6.0 % with carbon layer compared to 5.6 % without for 250 nm CIGS thickness).
