Photovoltaic technology with low weight, high specific power in cold environments, and compatibility flexible fabrication is highly desired for near-space vehicles polar region applications. Herein, we demonstrate efficient low-temperature perovskite solar cells by improving the interfacial contact between electron-transport layer (ETL) layer. We find that adsorbed oxygen active sites vacancies of tin oxide (SnO2 ) ETL can be effectively decreased incorporating a trace amount titanium tetrachloride (TiCl4 ). The effective defects elimination at increases electron mobility SnO2 layer, regulates band alignment perovskite/SnO2 interface, induces larger crystal growth, improves charge collection efficiency complete cell. Correspondingly, improved transforms into high-performance under one-sun illumination (AM 1.5G) efficiencies up to 23.7 % 218 K, which might open new era application this emerging photovoltaic environments such as regions.

Perovskite crystal facets greatly impact the performance and stability of their corresponding photovoltaic devices. Compared to (001) facet, (011) facet yields better photoelectric properties, including higher conductivity enhanced charge carrier mobility. Thus, achieving facet-exposed films is a promising way improve device performance. However, growth energetically unfavorable in FAPbI3 perovskites due influence methylammonium chloride additive. Here, 1-butyl-4-methylpyridinium ([4MBP]Cl) was used expose facets. The [4MBP]+ cation selectively decreases surface energy enabling plane. causes perovskite nuclei rotate by 45° such that stack along out-of-plane direction. has excellent transport properties can achieve better-matched level alignment. In addition, [4MBP]Cl increases activation barrier for ion migration, suppressing decomposition perovskite. As result, small-size (0.06 cm2) module (29.0 based on exposure achieved power conversion efficiencies 25.24% 21.12%, respectively.

Abstract Despite the outstanding power conversion efficiency (PCE) of perovskite solar cells (PSCs) achieved over years, unsatisfactory stability and lead toxicity remain obstacles that limit their competitiveness large‐scale practical deployment. In this study, in situ polymerizing internal encapsulation (IPIE) is developed as a holistic approach to overcome these challenges. The uniform polymer package layer constructed by thermally triggered cross‐linkable monomers not only solidifies ionic crystalline strong electron‐withdrawing/donating chemical sites, but also acts water penetration ion migration barrier prolong shelf life under harsh environments. optimized MAPbI 3 FAPbI devices with IPIE treatment yield impressive efficiencies 22.29% 24.12%, respectively, accompanied remarkably enhanced environmental mechanical stabilities. addition, toxic water‐soluble leakage minimized synergetic effect physical wall chelation conferred IPIE. Hence, strategy provides feasible route for preparing efficient, stable, eco‐friendly PSCs.
