Abstract :
In this work the morphology and performance of thin-film solar cells with a kesterite-type Cu2ZnSn(S, Se)4 absorber are investigated. The preparation is based on a metal salt solution with dimethyl sulfoxide as solvent, which is deposited on a molybdenum coated substrate via doctor-blade coating and subsequently annealed in selenium-containing nitrogen-atmosphere. To learn more about the originating trilayer structure of the absorber, precursor layers of different thickness were prepared and temperature and duration of the annealing process were varied.
