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

Abstract Wide‐bandgap mixed‐halogen perovskite materials are widely used as top cells in tandem solar cells. However, serious open‐circuit voltage ( V oc ) loss restricts the power conversion efficiency (PCE) of wide‐bandgap (PSCs). Herein, it is shown that resulting methylammonium vacancies induce lattice distortion chloride‐assisted film, an inhomogeneous halogen distribution and low . Thus, a strain regulation strategy reported to fabricate high‐performance PSCs. Rubidium (Rb) cations introduced fill A‐site vacancy caused by volatilization, which alleviates shrinkage crystal. The reduced increased halide ion migration barrier result homogeneous mixed‐halide film. Due improved carrier transport suppressed nonradiative recombination, Rb‐treated PSC (1.68 eV) achieves excellent PCE 21.72%, accompanied high 1.22 V. device maintains more than 90% its initial after 1500 h under 1‐sun illumination conditions.

Interface-induced nonradiative recombination losses at the perovskite/electron transport layer (ETL) are an impediment to improving efficiency and stability of inverted (p-i-n) perovskite solar cells (PSCs). Tridecafluorohexane-1-sulfonic acid potassium (TFHSP) is employed as a multifunctional dipole molecule modify surface. The solid coordination hydrogen bonding efficiently passivate surface defects, thereby reducing recombination. induced positive between ETLs improves energy band alignment, enhancing interface charge extraction. Additionally, strong interaction TFHSP stabilizes surface, while hydrophobic fluorinated moieties prevent ingress water oxygen, device stability. resultant devices achieve power conversion (PCE) 24.6%. unencapsulated retain 91% their initial after 1000 h in air with 60% relative humidity, 95% 500 under maximum point (MPP) tracking 35 °C. utilization molecules opens new avenues for high-performance long-term stable devices.

Formamidinium lead iodide (FAPbI3 ) perovskite possesses an ideal optical bandgap and is a potential material for fabricating the most efficient single-junction solar cells (PSCs). Nevertheless, large formamidinium (FA) cations result in residual lattice strain, which reduces power conversion efficiency (PCE) operational stability of PSCs. Herein, modulation strain FAPbI3 crystals via π-conjugated organic amine, i.e., 4-pyrene oxy butylamine (PYBA), proposed. PYBA pairs at grain boundary serve as template crystallization perovskite, thereby inducing highly oriented crystal pure α-phase film. The with strong π-π interactions provide solid fulcrum external compression thus compensating inherent tension crystals. release elevates valence band crystals, decreasing trap density. Consequently, PYBA-regulated PSC achieves excellent PCE 24.76%. Moreover, resulting device exhibits improves maintains over 80% its initial after 1500 h under maximum point tracking conditions.
