Abstract The field of solar systems has undergone rapid development with the emergence special material, perovskite. Perovskite's unique mechanism, defect tolerance, enabled perovskite cells (PSCs) to achieve high power conversion efficiencies (PCEs), and many studies on this subject have been conducted. “Defect tolerance” indicates that defects in are primarily generated at shallow‐energy level do not occur through nonradiative recombination. However, also well formed films shallow can transform into deep traps, leading long‐term stability issues. Therefore, controlling is essential for developing PSCs PCEs. causes diverse, patterns differ considerably, particularly depending location PSCs. In review, will be discussed review several methods passivating them different.

Abstract High‐boiling‐point nonhalogenated solvents are superior to produce large‐area organic solar cells (OSCs) in industry because of their wide processing window and low toxicity; while, these with slow evaporation kinetics will lead excessive aggregation state‐of‐the‐art small molecule acceptors (e.g. L8‐BO), delivering serious efficiency losses. Here, a heterogeneous nucleating agent strategy is developed by grafting oligo (ethylene glycol) side‐chains on L8‐BO (BTO‐BO). The formation energy the obtained BTO‐BO; changing from liquid solvent crystalline phase, lower than that irrespective type. When BTO‐BO added as third component into active layer PM6:L8‐BO), it easily assembles form numerous seed crystals, which serve nucleation sites trigger increase density through strong hydrogen bonding interactions even high‐boiling‐point solvents. Therefore, can effectively suppress during growth, achieving ideal phase‐separation domain sizes high crystallinity. resultant toluene‐processed OSCs exhibit record power conversion (PCE) 19.42% (certificated 19.12%) excellent operational stability. also has advantages large‐scale devices, showing 15.03‐cm 2 module PCE 16.35% 15.97%).

Abstract Organic self‐assembled molecules (OSAMs) based hole‐transporting materials play a pivotal role in achieving highly efficient and stable inverted perovskite solar cells (IPSCs). However, the reported carbazol‐based OSAMs have serious drawbacks, such as poor wettability for solution spreading due to nonpolar surface, worse matched energy arrangement with perovskite, limited molecular species, which greatly limit device performance. To address above problems, novel OSAM [4‐(3,6‐glycol monomethyl ether‐9H‐carbazol‐9‐yl) butyl]phosphonic acid (GM‐4PACz) was synthesized material by introducing glycol ether (GM) side chains at carbazolyl unit. GM groups enhance surface of Indium Tin Oxide (ITO)/SAM substrate facilitate nucleation growth up film, suppress cation defects, release residual stress SAM/perovskite interface, evaluate level matching perovskite. Consequently, GM‐4PACz IPSC achieves champion PCE 25.52 %, respectable open‐circuit voltage ( V OC ) 1.21 V, high stability, possessing 93.29 % 91.75 their initial efficiency after aging air 2000 h or tracking maximum power point 1000 h, respectively.

Flexible perovskite solar cells (pero-SCs) have the potential to overturn application scenario of silicon photovoltaic technology. However, their mechanical instability severely impedes practical applicability, and corresponding intrinsic degradation mechanism remains unclear.

To suppress failure, pentaerythritol triacrylate, a crosslinked molecule with three stereoscopic crosslink sites, employed establish 3D polymer network both interface bulk perovskite. This reduced Young's modulus simultaneously enhanced interfacial toughness. As result, formation cracks delamination, which occur high stress, significantly suppressed pero-SC, consequently retained 92% its initial power conversion efficiency (PCE) after 20 000 bending cycles.
