The dominant hole transport material in the state-of-the-art n-i-p perovskite solar cells (PSCs) mainly is Spiro-OMeTAD, which suffer from the instability issue caused by the intrinsic nature of additives and dopants. Here, a formate diffusion engineering of Spiro-OMeTAD is proposed to improve the s...
