We warmly congratulate Albert These on the successful defense of his PhD. In his PhD research, Albert These investigated defects in metal halide perovskites, focusing on their origin, characterization, and impact on solar cell performance. He developed and applied experimental approaches to identify and quantify defects, studied the mechanisms underlying defect tolerance, and explored how defects affect charge-carrier recombination and device operation. By combining advanced spectroscopic and optoelectronic characterization techniques with device-physics simulations, his work contributed to a deeper understanding of the relationship between defects and performance in perovskite solar cells. We congratulate Albert on this important achievement and wish him continued success in his future scientific career!
