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.

SummaryThe advent of metal-halide perovskite solar cells has revolutionized the field photovoltaics. The high power conversion efficiencies exceeding 26% at laboratory scale—mild temperature processing, possibility fabrication on multiple substrates, and easy composition-dependent band-gap tunability make perovskites suitable for both single-junction tandem-multijunction cells. They are attractive in various applications, from utility-scale to building-integrated indoor To bring maturity, next big step is funnel efforts into developing reproducible high-quality materials via high-throughput manufacturing, addressing issues inherent material instability. Another key issue environmental sustainability associated with presence lead. In this perspective, a special focus placed real-world applications photovoltaics, starting selection deposition techniques finally discussing stability how improve it toward wider industrialization.Graphical abstract

Perovskite solar cells (PSCs) suffer from a quick efficiency drop after fabrication, partly due to surface defects, and can be further enhanced with the passivation of defects. Herein, is reviewed as method improve both stability PSCs, an emphasis on chemical mechanism passivation. Various molecules are utilized passivants, such halides, Lewis acids bases, amines (some result in low-dimensional perovskite), polymers. Multifunctional promising group they capable passivating multiple defects various functional groups. This review categorizes these addition considering potential limitations each type passivant. Additionally, passivants for Sn-based PSCs discussed since this has poor photovoltaic performance compared their lead-based counterpart severe Lastly, future perspectives usage addressed provide direction upcoming research practical applications.

Controlling traps and structural defects in perovskite absorber layers is crucial for enhancing both the device efficiency long-term stability of solar cells (PSCs). Here we demonstrate modification films by introducing low-cost green polymers, polysuccinimide (PSI) polyasparagine (PASP), into layer. Structural, morphological optoelectronic properties polymer-modified were probed scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR) UV-Vis spectroscopy. The incorporation PSI triggers interactions between polymer perovskite, leading to passivation surface at grain boundaries improved morphology films. This defect boosted PSC performance, providing power conversion (PCE) values up 20.1%. An optimal concentration 0.1 mg/mL precursor solution was identified an improvement photovoltaic performance. It shown that primary factor observed enhancement PSI-modified PSCs increase lifetime charge carriers due efficient suppression recombination losses. Additionally, demonstrated enhanced stability, retaining over 80% their initial after 40 days storage under ambient conditions without encapsulation. obtained results highlight effectiveness additives passivating provide a viable approach improving performance cells.

Perovskite solar cells (PSCs) have demonstrated remarkably rapid efficiency improvements mainly through spin-coating-based solution processes. While these processes offer numerous advantages, there are also several limitations, prompting research into alternative fabrication methodologies for PSCs. Meanwhile, surface engineering has been identified as one of the most critical factors enhancing and stability For passivation, studies reported to date, especially n–i–p structures, relied on solution-based However, face challenges in controlling termination perovskite surfaces, achieving fine thickness control, dealing with lead halides that utilize common solvents perovskites. In this study, we introduce a strategy employing dry-vacuum deposition process deposit PbI2 PbCl2 nanoscale precision thin films. This is followed by vacuum alkyl (4-methoxy-phenethylammonium-iodide, MeO-PEAI), which improved photostability devices compared typical solution-processed MeO-PEAI treatment.

Abstract Historically seen as a limitation, grain boundaries (GBs) within polycrystalline metal halide perovskite (MHP) films are thought to impede charge transport, adversely impacting the efficiency of solar cells (PSCs). In this study, we employ home-built confocal photoluminescence microscopy, combined with photocurrent detection modules, directly visualize carrier dynamics in MHP film PSCs under real operating conditions. Our findings suggest that GBs high-efficiency function transport channels, where notable enhancement is observed. Femtosecond transient absorption and Kelvin probe force microscopy measurements further validate existence built-in electric field vicinity GBs, offering additional driving for separation establishing channels swift along thereby expediting subsequent collection processes. This study elucidates pivotal role operational provides valuable insights fabrication PSCs.
