However, these high performances are still mainly obtained via spin-coating and halogenated solvents, which limits scalability and environmental compatibility. Developing efficient devices under green, air-processed conditions therefore remain a key challenge, particularly due to the strong sensitivity of polymer morphology. Here, we investigate PM6:PY-IT-based all-PSCs processed by air doctor-blade coating using o-xylene as a nonhalogenated solvent, together with a PM6:Y12 binary reference and an advanced ternary PM6:Y12:PY-IT system. We systematically examine the influence of electron transport layers (PDINN, PFN-Br, and PNDIT-F3N) and processing additives (Tetralin and DMN) on morphology, charge transport, device performance, and stability. The devices are characterized using J–V measurements, grazing-incidence wide-angle X-ray scattering, atomic force microscopy, space-charge-limited current, and ISOS-D-1, ISOS-D-2, and ISOS-L-1 protocols. PM6:PY-IT devices processed with DMN reach a PCE of 16.58% in small areas, and 10.91% upon scaling to 1 cm2. DMN enhances molecular ordering, crystallinity, and charge transport compared to Tetralin, particularly in PY-IT-based systems, leading to higher fill factors and performances. While the highest efficiency is obtained with PDINN, PNDIT-F3N offers the best balance between efficiency and stability.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 17","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.70471","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148943737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deep level transient spectroscopy (DLTS) reveals three signatures: H1, H2, and N1. H1 and H2 are attributed to hole traps within the material bulk, and N1 is attributed to the back contact barrier. The H2 trap acts as a recombination center and is found to affect the room temperature capacitance–voltage (C–V) results, necessitating “fast C–V” measurements. The N1 signature has increasing activation energy (barrier height) with increasing RbF dose, and good quantitative agreement is obtained between energies measured using DLTS and admittance spectroscopy, as well as qualitative agreement with current–voltage–temperature (J–V–T) measurements. Macroscale SIMS and nanoscale transmission electron microscopy-based X-ray energy dispersive spectroscopy measurements reveal Rb accumulation at the ACIGS/MoSe2 interface that increases, along with Rb concentration in the ACIGS bulk, with increasing RbF dose. The accumulation of compensating charges near this interface is proposed to be the explanation for the increased back contact barrier height observed here.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 17","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148943656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review focuses on the most recent progress of IPSCs and systematically probes into the importance and mechanisms governing the buried interface by analyzing challenges associated with interface defects, energy-level mismatch, chemical stability, and morphological uniformity. It comprehensively reviews the advancements in diverse buried-interface strategies from the molecular perspective, including organic materials (organic small molecules and polymers), inorganic salts, and low-dimensional materials (2D layer or 2D/3D heterojunctions, 1D materials, and 0D materials). Furthermore, advanced characterization techniques for the buried interface are summarized focusing on their ability to analyze morphological structure, chemical and electronic states, and carrier dynamics.

In this article, rapid annealing (temperature range 600–700 °C, heating rate 40 °C s−1) was performed on GaInP/GaAs/Ge solar cells, revealing that high-temperature annealing would cause a significant reduction in the power conversion efficiency (PCE) of devices. Furthermore, a variety of advanced characterization techniques, including time-of-flight secondary ion mass spectrometry, in situ variable-temperature high-resolution transmission electron microscopy, and scanning electron microscopy analysis, were used to systematically study the impacts of annealing conditions on the performance of GaInP/GaAs/Ge solar cells as well as the performance degradation mechanisms. It is revealed that high-temperature annealing induces a variety of negative impacts to GaInP/GaAs/Ge solar cells, such as back electrode damage, interfacial element diffusion, and semiconductor material failure, which further inhibit the carrier collection and destroy the junction regions between sub-cells. Eventually, these unfavorable consequences lead to a significant reduction in the device PCE and even cause complete device operation failure.

Herein, we introduce a multifunctional ionic liquid, N-butylsulfonate pyridinium hydrogensulfate (BSPH), to simultaneously regulate crystallization kinetics and defect chemistry in WBG perovskites. Owing to its amphiphilic molecular architecture containing sulfonate, hydrogen sulfate, and pyridinium moieties, BSPH establishes dynamic multisite interactions with perovskite precursors. BSPH not only coordinates strongly with undercoordinated Pb2+ species, but also forms extensive electrostatic and hydrogen-bonding interactions with FA+ cations and halide ions, creating a stabilized intermediate-state network during film formation. It effectively suppresses rapid crystallization and regulates crystallization kinetics. Furthermore, the coupled hydrogen-bond networks and electrostatic interactions effectively suppress ion migration and defect formation, leading to reduced trap-state density, suppressed nonradiative recombination, and prolonged carrier lifetime. As a result, the optimized PSC achieves a champion power conversion efficiency of 23.72% and retains over 84.5% of its initial efficiency after 600 h maximum power point tracking.

In most down-shifting studies, the isotropic emission of down-shifting materials limits the photon utilization. Herein, we combine inverted-pyramid texturization with luminescent down-shifting films to minimize broadband reflection of photovoltaic devices and enhance the utilization of down-shifted photons. The textured architecture increases the energy transfer efficiency of down-shifted photons to 1.3 times that of a flat down-shifting film. For silicon solar cells, the textured down-shifting film yields a total integrated photocurrent enhancement of 2.3% over its flat counterpart. Of this improvement, 0.2% is attributed to the enhanced redirection of down-shifted photons toward the solar cell in the UV region (300–400 nm), while 2.1% originates from broadband light-trapping effect across the full spectrum (400–1180 nm), resulting in a relative efficiency gain of 2.0%. The same strategy is further extended to wide-bandgap perovskite solar cells, delivering a relative efficiency improvement of 2.3% with respect to bare devices, demonstrating the applicability of this optical management approach beyond silicon-based technologies. This work provides insights into the underlying physical phenomena of textured luminescent down-shifting film and optimal design considerations for encapsulation materials in high-performance photovoltaic devices.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 16","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148784087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
