摘要： Adding additives into peroskite precursor solution has been proven as a simple and efficient strategy to improve the quality of peroskite films. In this work, we demonstrate an effective additive strategy to improve the quality of all-inorganic perovskite films by adding a novel silazane additive heptamethyldisilazane (HDMS). The power conversion efficiency (PCE) of the optimized devices is enhanced from 14.55% to 15.31% with an open-circuit voltage over 1.26 V due to the higher quality perovskite films with lower trap density after the incorporation of HDMS. More interestingly, the HDMS devices exhibit superior humidity and thermal stability compared with the control ones. This work provides a simple and efficient strategy to enhance the device performance and stability of all-inorganic perovskite solar cells, which could facilitate its commercialization.
