摘要
Organic–inorganic hybrid perovskites have taken the center stage in the solar cell field, with power conversion efficiencies(PCE) values exceeding 22%.It has always been an essential issue to achieve a delicate control of perovskite materials growth, and thus the resulted device performance.Here, starting from precursor chemistry, we thoroughly studied the coordination effect and intercalation reaction during hybrids perovskite crystallization.We successfully synthesized high quality perovskite thin film by controlling the nucleation/growth rate and chemical reaction.One example is that by introducing weak coordination additive or base environment in the precursor, the corresponding perovskite film shows extraordinary large grain size, crystallinity, and carrier lifetime, leading to an enhanced efficiency of ~20 % under low temperature.Additionally, the generality of the proposed film growth mechanism have been confirmed in the perovskite materials system by using additives of various coordination abilities, which further enriches the details in the full picture of hybrids perovskite film growth.
