Abstract Porous lead iodide (PbI 2 ) film is crucial for the complete reaction between PbI and ammonium salts in sequential‐deposition technology so as to achieve high crystallinity perovskite film. Herein, it found that tensile stress tin (IV) oxide (SnO electron transport layer (ETL) a key factor influencing morphology crystallization of films. Focusing on this, lithium trifluoromethanesulfonate (LiOTf) used an interfacial modifier SnO /PbI interface decrease reduce necessary critical Gibbs free energy nuclei formation. The relaxed facilitates more porous generation with larger particles higher roughness, resulting superior‐quality Besides, this strategy effectively passivates inherent traps smooths levels, boosting charge extraction transfer. As result, champion power conversion efficiency (PCE) 25.33% (25.10% stabilized 600 s) achieved. Furthermore, device demonstrates exceptional stability, retaining 90% its initial PCE at maximum point tracking measurement (under 100 mW cm −2 white light illumination ≈55 °C temperature, N atmosphere) after h.

Buried-interface engineering is crucial to the performance of perovskite solar cells. Self-assembled monolayers and buffer layers at buried interface can optimize charge transfer reduce recombination losses. However, complex mechanisms difficulty in selecting suitable functional groups pose great challenges. Machine learning (ML) offers a powerful tool for screening identifying effective structures modification. Our ML-driven approach led preparation two promising organic molecules, PAPzO PAPz, which exhibit synergistic interactions with SnO2 perovskites. These molecules decrease trap densities, elongate carrier lifetimes, retard crystallization. PAPzO, stronger binding energy better aligned levels, enables power conversion efficiency (PCE) 26.04% long-term stability, maintaining 91.24% its original PCE after 1,200 h continuous maximum point tracking. This ML-integrated marks significant advancement development efficient stable photovoltaics.

Abstract The sol–gel method is efficient and cost‐effective for synthesizing SnO 2 sol, wherein nanocrystallites (NCs) are stabilized by electric double‐layer of solvated ions tightly bound to their surface. However, this strong binding makes the removal residues from electron transport layer (ETL) be difficult at low temperatures. This hinders both close contact subsequent growth among adjacent NCs, leading severe carriers scattering grain boundary, adversely affecting electrical properties ETL. Herein, sol synthesized via an ethanol‐based aqueous ammonia (NH 3 ·H O) introduced effectively clean stubborn within ETL a temperature (80 °C). Removing reduces gap NCs promotes further reconstructed through oriented attachment (OA), thereby reducing number boundaries. Hence, energy barriers decrease Furthermore, MHP prepared on treated has fine‐tuned level alignment, improving extraction capacity. Consequently, flexible perovskite solar cells (f‐PSCs) incorporating achieved notable increase in power conversion efficiency, rising 19.16% 23.71%, as well superior mechanical stability.

Abstract Tin oxide (SnO 2 ) with high conductivity and excellent photostability has been considered as one of the most promising materials for efficient electron transport layer (ETL) in perovskite solar cells (PSCs). Among them, SnO nanoparticles (NPs) dispersions have extensively utilized due to their facile film formation. However, inherent defects agglomeration issues NPs, well limited tunability instability post‐treatment process surface/interface engineering strategy, still hinder its further applications. Herein, a ligand‐management strategy implemented during situ synthesis NPs that can effectively achieve uniform modification is proposed. During grafting reaction between diethyl 2‐chloromalonate (DCMA) surface completed. Compared process, this intrinsic DCMA‐passivated (DCMA‐SnO reduces trap state density at interface ETL while enhancing chemical stability. Consequently, PSCs based on DCMA‐SnO champion PCE 25.39% small (active area 0.0655 cm 20.61% modules 23.25 ), demonstrating shelf‐life/light soaking stability (advanced level ISOS protocols). This exhibits significant application potential preparing high‐efficiency large‐area PSCs.

Perovskite solar cells (PSCs), which are constructed using organic-inorganic combination resources, represent an upcoming technology that offers a competitor to silicon-based cells. Electron transport materials (ETMs), essential PSCs, attracting lot of interest. In this section, we begin by discussing the development PSC framework, would form foundation for requirements ETM. Because their exceptional electronic characteristics and low manufacturing costs, perovskite (PSCs) have emerged as promising proposal future generations thin-film energy. However, PSCs with compact layer (CL) exhibit subpar long-term reliability efficacy. The quality substrate beneath has major impact on how quickly it grows. Therefore, there been interest in modification electron transfer layers create very stable efficient PSCs. This paper examines systemic alteration (ETLs) based employed Also covered functions ETLs creation reliable Achieving larger-sized particles, greater crystallization, more homogenous morphology within films, all correlated performance, will be guided review when they developed further. To increase PSCs' sustainability enable them produce clean energy at levels previously unheard of, difficulties potential paths research also discussed.
