Metal halide perovskites, a rising star in semiconductor materials, boast exceptional optoelectronic characteristics. These include high absorption coefficients, easily adjustable optical bandgaps, high electron-hole mobility, and long carrier diffusion lengths. Owing to these attributes, they hold immense potential for applications in solar cells, LEDs, and X-ray detectors. Notably, perovskite solar cells have drawn considerable interest from research institutions and the industrial community, thanks to their high efficiency, cost-effectiveness, and solution-processability. Lately, the research team spearheaded by Professor Zhengguo Xiao from our university's School of Physics, in partnership with the research groups led by Professor Shangfeng Yang and Professor Weiren Cheng from the School of Chemistry and Materials Science, has achieved a series of breakthroughs in the development of highly efficient and stable inverted perovskite solar cells. Their work has been featured in multiple papers published in internationally acclaimed journals.
