The perovskite layer contains a large number of charged defects that seriously impair the efficiency and stability of perovskite solar cells (PSCs), thus it is essential to develop an effective passivation strategy to heal them. Based on theoretical calculations, it is found that enhancing the electrostatic potential of passivators can improve passivation effect and adsorption energy between charged...
With its power conversion efficiency surpassing those of all other thin‐film solar cells only a few years after its invention, the perovskite solar cell has become a superstar. Controlling the intermediate phase of crystallization is a key to obtaining high‐quality perovskite films. Herein, a single molecule additive, N,N‐dimethylimidodicarbonimidic diamide hydroiodide (DIAI), is incorporated into...
