Short presentation

My research focuses on hybrid perovskite solar cells, employing HAXPES to investigate chemical interactions at the interface between the transport and absorber layers under the operating conditions, such as light illumination and applied bias. This approach provides a deeper understanding of the interfacial processes, which is crucial for optimising the stability and performance of these solar cells.
