  2. 6. On Generation and Recombination in Cu(In,Ga)Se2 Thin-Film Solar Cells

    Author : Jonas Malmström; Lars Stolt; Uwe Rau; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; solar energy conversion; solar cells; Cu In; Ga Se2; device modelling; optical properties; electron-hole generation; light trapping; electron-hole recombination; Elektronik; Electronics; Elektronik;

    Abstract : The solar cell technology based on Cu(In,Ga)Se2 (CIGS) thin-films provides a promising route to cost competitive solar electricity. The standard device structure is ZnO:Al/ZnO/CdS/CIGS/Mo films on a glass substrate, where the first three layers are n-type semiconductors with wide bandgaps, forming a pn-junction with the p-type CIGS absorber layer; the Mo layer serves as a back contact.
