Energy center Assistant Professor Selgey Luchkin gave a lecture “Stability of perovskite solar cells: A case of photo-induced phase segrregation”
Abstract:
Achieving long-term operational stability of perovskite solar cells is crucial for their integration into high-efficiency tandem architectures. One of the major challenges is photoinduced phase segregation in mixed-halide perovskites, which affects bandgap stability and device performance. The talk will provide insights into the mechanisms driving phase segregation under illumination and discuss material design strategies to suppress degradation.
