“…As illustrated in Figure 1a, these calculations revealed strong interactions between DDS/SDP and lead/iodine due to electron-rich and electron-deficient groups. [29][30][31] Figure 1b depicts the schematic diagram of perovskite film post-treated by DDS and SDP. DDS and SDP were dissolved in IPA, spin coated on perovskite film, and annealed for 10 min.…”

The efficiency of perovskite solar cells (PSCs) is hindered by substantial defects within the grain boundaries (GBs) of polycrystalline perovskite films. Conventional post‐treatment strategies struggle to precisely repair these defects at GBs. Here, a targeted grain boundary passivation strategy through solvent effects by incorporating symmetrical biphenyl molecules is proposed, 4,4′‐diaminodiphenyl sulfone (DDS) and 4,4′‐sulfodiphenol (SDP), aiming to mitigate defects at GBs and optimize energy level arrangements through their electric dipole effects. Compared to the pristine device, the SDP‐modified device exhibits significant improvements, including a champion efficiency of 24.39% and an impressive fill factor, along with excellent operation stability. This work provides an effective and straightforward solution for improving the performance of PSCs.
