  • Abstract
    The impact of sulfur incorporation and its content in the Cu(In,Ga)(Se,S)2 layer with respect to a bandgap widening and an improvement of absorber quality has been investigated. A theoretical method to quantitatively estimate the minority carrier lifetimes based on experimental temperature dependent Voc measurements is presented. The often observed discrepancy between lifetime measurements on the bare Cu(In,Ga)(Se,S)2 films and completed devices is discussed.
