Abstract Over the last decade, perovskite solar cells (PSCs) have drawn extensive attention owing to their high power conversion efficiency (single junction: 26.1%, perovskite/silicon tandem: 33.9%) and low fabrication cost. However, short lifespan of PSCs with initial still blocks practical applications. This operational instability may originate from intrinsic extrinsic degradation materials or devices. Although lifetime has been prolonged through component, crystal, defect, interface, encapsulation engineering, so on, systematic analysis failure regularity for perspective devices against multiple operating stressors is indispensable. In this review, we start elaboration predominant pathways mechanism under working stressors. Then strategies improving long‐term durability respect fundamental materials, interface designs, device summarized. Meanwhile, key results discussed understand limitation assessing stability, potential applications in indoor photovoltaics wearable electronics are demonstrated. Finally, promising proposals, encompassing material processing, film formation, strengthening, structure designing, encapsulation, provided improve stability promote commercialization. image

Abstract Wide‐bandgap (WBG) perovskite solar cells (PSCs) have drawn great attention owing to their promising potential for constructing efficient tandem cells. However, the rapid crystallization results in poor film properties and easy formation of defects, thereby greatly restricting acquisition a small open‐circuit voltage ( V OC ) deficit due severe nonradiative recombination. Herein, it introduced triethanolamine borate (TB) effectively slow down preparing highly crystalline uniform WBG films with reduced defects. The strong intermolecular interaction (e.g., coordination hydrogen bond) between TB can suppress halide vacancy inhibit phase segregation improving long‐term stability. devices based on 1.65 eV absorber achieved high efficiency 21.55% 1.24 V, demonstrating is as low 0.41 which one lowest reports. By combining semitransparent subcell narrow‐bandgap tin‐based PSC, four‐terminal cell delivers 26.48%.

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Июнь 12, 2024

Abstract The self‐assembled monolayer (SAM) is now widely applied at the hole‐selective interface of efficient inverted perovskite solar cells (PSCs). However, voids are unavoidable in SAMs due to rough substrate and deposition conditions, which lead direct contact between active layer electrode, undermining efficiency stability PSCs. Here, alkylphosphonic acids with different alkyl chain length post‐assembled fill voids, thereby forming a compact po‐SAM layer. By further modifying head group acids, PSCs improved wetting passivation. Finally, formed by (2‐Bromoethyl) phosphonic acid [4‐(3,6‐dimethyl‐9H‐carbazol‐9‐yl)butyl] contributes champion device power conversion 25.16% (certified 24.67%) under operation or storage.
