摘      要：Adding additives into peroskite precursor solution has been proven as a simple and efficient strategy to improve the quality of peroskite *** 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 *** interestingly,the HDMS devices exhibit superior humidity and thermal stability compared with the control *** 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.
