Abstract Perovskite solar cells have achieved remarkable progress in photovoltaic performance, driven by advancements interface engineering. The buried between the electron transport layer and perovskite is particularly critical, as it governs both crystallization formation of residual strain. In this study, printable mesoscopic (p‐MPSCs) based on a triple‐mesoporous scaffold TiO 2 /ZrO /carbon reconstructed employing dodecaethylene glycol (DEG), long chain molecule rich polar oxygen atoms, to enhance device performance. Treating with DEG optimizes wettability sequence across three layers improving surface's wettability, facilitating preferential underlying layer. Moreover, effectively buffers strain suppresses detrimental defects at interface. As result, p‐MPSCs optimized achieve power conversion efficiency (PCE) 20.27% retain over 92% their initial PCE after 500 h continuous operation under maximum point tracking.

Carbon-based hole transport layer-free (C-HTL-free) perovskite solar cells (PSCs) are promising for low-cost and stable photovoltaics, but the HTL absence deteriorates their power conversion efficiency (PCE) due to lack of back surface field (BSF). In this work, benefits forming dual BSFs in improving PCE C-HTL-free PSCs first investigated by simulation. Then, trityl tetrakis(pentafluorophenyl)borate (Tr+TPFB-) is introduced into post-treatment time, which enables formation BSFs. TPFB- passivates n-doping defects leads n-p homojunction, while Tr+ extracts electrons from carbon lowers its work function, succeeds realizing This improves separation extraction photocarriers within device, evidenced photoluminescence lifetime imaging device cross-section time. As a result, average open-circuit voltage increases significantly about 70 mV, largely contributes improvement with champion value 20.79% obtained.

Low‐temperature‐processed carbon‐based perovskite solar cells (C‐PSCs) are a potential candidate for industrial development, due to their low cost, high stability, and easy preparation methods. However, power conversion efficiencies still lag behind that of metal‐contact‐based PSCs, poor compatibility the carbon electrode with underlying layers. Here, we introduce doping‐free poly(3‐hexylthiophene) (P3HT) hole‐transport layer deposited from chloroform improve cell performance PSCs prepared in ambient air. The resulting P3HT films have lower roughness higher conductivity. A champion device efficiency 19.4% was obtained negligible hysteresis remarkably enhanced fill factor (FF) 80.2%. Unencapsulated devices maintained 70% initial value after 350 hr under thermal stress at 85°C dark
