Abstract Currently, the photovoltaic performance of perovskite solar cells (PSCs) is closely linked to undermined defects in perovskite, and correct approach ensure stability under practical conditions still dispute. Therefore, natural, healthy, low‐cost additives are expected not only reduce trap sites but also drastically improve stability. In this work, natural antioxidant additive lycopene extracted from tomatoes introduced into PSCs. The results indicate that can passivate grain boundaries, crystallinity, density, facilitate α phase formation at room temperature. As a result, power conversion efficiency (PCE) considerably improved 20.57% 23.62% with vastly enhanced J sc V oc . Additionally, eliminate UV‐induced free radicals light aging process. target device displays hydrophobic, antioxidative properties, which demonstrates high O 2 91.2% average PCE for 960 h, UV long‐term an 92.4% after 3500 h.

Abstract Perovskite solar cells (PSCs) have become a promising photovoltaic (PV) technology, where the evolution of electron‐selective layers (ESLs), an integral part any PV device, has played distinctive role to their progress. To date, mesoporous titanium dioxide (TiO 2 )/compact TiO stack been among most used ESLs in state‐of‐the‐art PSCs. However, this material requires high‐temperature sintering and may induce hysteresis under operational conditions, raising concerns about its use toward commercialization. Recently, tin oxide (SnO ) emerged as attractive alternative ESL, thanks wide bandgap, high optical transmission, carrier mobility, suitable band alignment with perovskites, decent chemical stability. Additionally, low‐temperature processability enables compatibility temperature‐sensitive substrates, thus flexible devices tandem cells. Here, notable developments SnO perovskite‐relevant ESL are reviewed emphasis placed on various fabrication methods interfacial passivation routes champion Further, techno‐economic analysis materials for large‐scale deployment, together processing‐toxicology assessment, is presented. Finally, perspective how can be instrumental successful module perovskite‐based cell manufacturing provided.

Abstract The perovskite solar cell has emerged rapidly in the field of photovoltaics as it combines merits low cost, high efficiency, and excellent mechanical flexibility for versatile applications. However, there are significant concerns regarding its operational stability robustness. Most previously reported approaches to address these entail separate engineering charge-transporting layers. Herein we present a holistic design layers by synthesizing an interpenetrating perovskite/electron-transporting-layer interface. This interface is reaction-formed between tin dioxide layer containing excess organic halide lead halide. Perovskite cells with such interfaces deliver efficiencies up 22.2% 20.1% rigid flexible versions, respectively. Long-term (1000 h) demonstrated devices show endurance against mechanical-bending (2500 cycles) fatigue. Mechanistic insights into relationship structure performance enhancement provided based on comprehensive, advanced, microscopic characterizations. study highlights integrity important factor designing efficient, operationally-stable, mechanically-robust cells.
