Imperfections and their passivation in halide perovskite solar cells
Bo Chen, Peter N. Rudd, Shuang Yang, Yongbo Yuan, Jinsong Huang- General Chemistry
Perovskite solar cells to date are made of polycrystalline films which contain a high density of defects. Imperfection passivation to reduce non-radiative recombination and suppress ion migration could improve device efficiency and device stability.
