Abstract The complete phase transition from DMAPbI 3 and Cs 4 PbI 6 intermediates to the final CsPbI perovskite is pivotal for fabricating high‐quality inorganic films. In this study, reaction energy barrier between sought be reduced by increasing their surface energy, where a perfluorinated compound designed using DFT modeling saturate of effectively prevent crystalline growth. Consequently, smaller with ultrahigh react more energetically facilitate rapid conversion desired phase. It found that resultant shows improved crystallinity morphology, as demonstrated suppressed non‐radiative recombination prolonged carrier lifetimes. As result, optimized solar cells (PSCs) achieve power efficiency (PCE) over 20%, along significantly light thermal stability. This work provides way regulate crystallization dynamics advanced quality perovskites.

Abstract Thermally induced tensile strain that remains in perovskite films after annealing is one of the key reasons for diminishing performance and operational stability solar cells (PSCs). Herein, a glass transition temperature ( T g ) regulation (TR) strategy developed by introducing two polymerizable monomers, 2‐(N‐3‐Sulfopropyl‐N, N ‐dimethyl ammonium)ethyl methacrylate (SBMA) 2‐Hydroxyethyl acrylate (HEA), into layer. SBMA HEA undergo situ polymerization, which regulates nucleation crystal growth film. In addition, adjusting ratio to lower resulting polymer effectively releases The modified film exhibits significantly reduced strain, decreased trap density improved stability. As result, optimized PSCs achieve champion power conversion efficiency (PCE) 26.15% (certified as 25.59%). Furthermore, encapsulated device demonstrates prominent enhanced operation stability, maintaining 90.3% its initial 500 h continuous sunlight exposure.

Interface engineering has significantly boosted perovskite solar cell efficiency and stability. However, numerous approaches focus on addressing defects at the interfaces between transport layers while neglecting potential issues within bulk material. Here, a multifunctional molecule, sodium lignosulfonate (SL), containing three types of functional groups, was introduced as chemical bridge perovskite/SnO2 interface. The SL bridges promote energy level alignment interface regulate crystallization process. Meanwhile, coordinated interactions components with −OH −SO3– groups SL, coupled Na+ diffusion, effectively passivate buried bulk. As result, champion SnO2–SL based n-i-p PSC achieved power conversion efficiencies 25.73% 25.13% rigid flexible substrates, respectively. Unencapsulated devices maintained 92.9% their initial after 2,550 h maximum point-tracking under 1-sun illumination in an inert atmosphere.
