New Method To Improve Performance Of All-perovskite Tandem Solar Cells

According to Xinhua News Agency, after long-term research, a Chinese scientific research team has made new progress in exploring the performance improvement of all-perovskite tandem solar cells. They creatively proposed a comprehensive doping strategy of aspartate hydrochloride, which effectively improved the narrow band gap. The efficiency and stability of perovskite sub-cells find new ways to further improve battery performance.
According to reports, the new metal halide perovskite has the advantages of simple preparation process, high defect tolerance, high absorption coefficient, and long carrier diffusion length. It has attracted much attention in the field of optoelectronic devices and is considered by the industry to be a promising next generation technology. One of the first generation photovoltaic materials.
