The scientific research team in China has found a new way to improve the performance of all-perovskite laminated solar cells, and the research results are published in the journal Nature.

Thanks to CTOnews.com netizen Xiao Zhan for the clue delivery! CTOnews.com, November 12, according to the official website of the School of physical Science and Technology of Wuhan University, a team of professors Ke Weijun and Fang Guo of the School of physical Science and Technology of Wuhan University recently made new progress in exploring the performance improvement of all-perovskite laminated solar cells, and their latest research results were published in the journal Nature.

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, so it has attracted much attention in the field of optoelectronic devices. it is considered to be one of the next generation photovoltaic materials with great prospect in the industry. Among them, the photoelectric conversion efficiency of single perovskite solar cells is equivalent to that of traditional silicon-based cells, but it will be more and more difficult to further improve its efficiency.

For this reason, the scientific research team creatively put forward the aspartate integrated doping strategy, which effectively improved the efficiency and stability of narrow band gap perovskite subbatteries. The steady-state efficiency of 27.62% (the third-party authoritative certification efficiency of 27.34%) is one of the highest in the world, and a new way to further improve the performance of the battery is found.
