Perovskite solar cell based on self-disintegrating seeds achieves 23.73% efficiency, 83.64% fill factor

A Chinese research group including scientists from module maker Tongwei has designed a perovskite solar cell with remarkable perovskite film quality through the so-called self-disintegrating seed strategy. The device not only achieved one of the highest fill factor values ever recorded for perovskite solar to date, but also showed remarkable stability. Researchers in China claim to have achieved one of the highest fill factor values for a perovskite solar cell by reducing its nonradiative recombination and residual stress through what they called a self-disintegrating seed strategy. "This strategy ...
