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

Researchers in China have achieved a high fill factor for a perovskite solar cell by using a self-disintegrating seed strategy to reduce nonradiative recombination and residual stress. The strategy enhanced perovskite grain growth, morphology optimization, and stress releasement through functional cations released from the seed. The new solar cell concept improved carrier lifetime, with tested efficiency reaching 23.73%, open-circuit voltage of 1.133 V, short-circuit current density of 25.21 mA cm2, and a fill factor of 83.07%.
