Abstract To address the challenge of upscaling single‐junction perovskite photovoltaics (PV) toward market‐relevant performance in a structured and efficient manner, stage‐gate approach that divides process into stages according to technology readiness levels (TRLs) is proposed. Whereas first stage contains only material research, later are concerned with development from lab‐scale devices large‐area modules, properties such as device size well processing methods adapted step‐by‐step commercializable techniques. The connected by gates specify criteria must be met for or transferred next stage. In addition, literature survey keywords “perovskite” “module” performed. This analysis shows most reported modules have an area between 10 cm 2 20 , corresponding 3 TRL 5 scheme, operational stability often incompletely reported. These findings indicate significant gap research focus on elevated stress field tests, which essential transitioning commercial applications. It suggested use proposed guideline commercializing PV.

Recent progress in inverted perovskite solar cells (IPSCs) mainly focused on NiOx modification and (PVK) regulation to enhance efficiency stability. However, most works address only monofunctional modifications, identical molecules with the ability simultaneously optimize interface bulk phase have been rarely reported. This work proposes a dual approach using 4-amino-3,5-dichlorobenzotrifluoride (DCTM) both upper interfaces reduction of defects perovskite. Amino group DCTM increases Ni3+/Ni2+ ratio NiOx, thereby increasing conductivity optimizing energy alignment. Additionally, fills Pb2+ I– vacancies perovskite, which improves vertical orientation grains subsequently reduces nonradiative recombination, achieving increased carrier lifetime. PVK modified by exhibits enhanced level alignment electron transport layer, while femtosecond transient absorption (TA) spectroscopy confirms that facilitates efficient transport, leading high-performance IPSCs. The optimized IPSCs achieve maximum 22.8% reduced hysteresis (0.7%). Moreover, unencapsulated device preserves over 80% its initial power conversion (PCE) after 1000 h stored air at 30% relative humidity. strategy monomolecular offers straightforward solution for optimization provides new insights into selecting aniline-derived

The phosphonic acid‐like anchoring group coupled with its large molecular size drives migration NDP toward indium tin oxide (ITO) surface to form a distinct ETL during film forming. This circumvents critical wetting issue simultaneously improves interfacial charge collection efficiencies. Consequently, n‐i‐p PSCs based on blended achieve champion power conversion efficiency (PCE) 24.01%, which one highest values using organic ETLs. performance notably higher than that ETL‐free (21.19%) independently spin‐coated (21.42%) counterparts.

Hybrid organic-inorganic halide perovskites (HOIPs) have garnered a significant amount of attention due to their exceptional photoelectric conversion efficiency. However, they still face considerable challenges in large-scale applications, primarily instability. One key factor influencing this instability is the lattice softness attributed A-site cations. In study, we investigated effects four different cations (MA, FA, EA, and GA) on by using combination ab initio molecular dynamics first-principles calculations. Our results demonstrate that an increase number hydrogen bonds for correlates with enhanced atomic fluctuations, resulting reduction bulk modulus softness. The strength bonding cation increases rotational energy barrier cation, along formation kinetic coupling between [PbI6]4- octahedron. Consequently, lifetime enhances rigidity perovskite lattice. Notably, found EA cations, which exhibit stronger fewer total bonds, can limit rotation inhibit rocking motion octahedron, thereby inherently soft lattice, ultimately enhancing stability material. findings elucidate effect perovskites, providing valuable theoretical insights design more stable HOIPs.

Solution-processed perovskite solar cells (PSCs) generally suffer from serious Pb-based defects, and the issue becomes more pronounced during upscaling process. A universal strategy that bridges small-area devices large-area modules is imperative for advancing PSC technology lab toward market readiness. Here, to effectively address defect proliferation issues of surfaces, an N,N-maleoyl-glycine (NMG) post-treatment anchoring was proposed. Precise defects achieved due strong Lewis acid-base interactions between NMG functional molecules perovskites. Consequently, a relatively high power conversion efficiency (PCE) 25.45% devices, greatly improved open-circuit voltage (Voc) fill factor (FF). More importantly, impressive PCEs 19.58% (with regular n-i-p configurations) 18.75% inverted p-i-n were with active area 64 cm2, confirming their compatibility Furthermore, unencapsulated NMG-based maintain than 90% initial PCE after continuous 1 sun illumination 1000 h under maximum point (MPP) tracking, demonstrating exceptional operational stability.
