Beschreibung

Research Goal

Flexible solar cells with a thin-film absorber made from Cu(In,Ga)Se2 can be industrially manufactured on stainless steel foils, and the efficiency has recently been improved further by replacing part of the Cu with Ag. However, inhomogeneities of the charge-collection efficiency at the nanoscale have been observed that limit the overall efficiency. Within this project, such inhomogeneities in industrial solar cells shall be investigated and correlated with the elemental distribution to unveil the mechanisms responsible for local underperformance. Ultimately, a comprehensive understanding of the inhomogeneities will allow to eliminate defects and contribute to the design of solar cells with even greater efficiency.
