Abstract Defects at the interface between perovskite and carrier transport layer are ≈100 times more prevalent than those within bulk, potentially serving as non‐radiative recombination centers to adversely affect extraction transport. Here, a green pyridoxine hydrochloride (PDHC) is introduced into SnO 2 quantum dots (QDs) solution. The resulting surface chloritization of QDs not only passivates defects, thereby strengthening contact among QDs, but also chemically interconnects with perovskite, forming very stable interlayer. These promote establish bridges buried interfaces for efficient electron‐transportation ‐extraction. Under its organic group coordination, high‐quality films formed via heterogeneous nucleation on precursor film, effectively suppressing bulk which mitigates nonradiative extends lifetime. Consequently, PDHC‐based solar cells achieve an improved efficiency from 24.18 25.07%. After 2520 h storage, unencapsulated devices retained ≈90% their initial efficiency, exceeding control 65% along 9.4 3.8‐fold improvement thermal light stability.

Abstract Perovskite solar cells (PSCs) have shown high power conversion efficiency in solar‐to‐electricity applications. However, the commercialization of this emerging technology is limited due to its low stability under realistic operating conditions. A major reason for degradation formation and escape iodine species upon exposure light, polarization thermal stress. Here, a new method proposed confine perovskite layer using multifunctional nitrogen‐rich covalent organic framework (TAPT‐BP‐COF). The ordered pore structure surface binding groups TAPT‐BP‐COF not only facilitate charge transfer complexes with molecules, but also enable multisite chelation undercoordinated lead ions, thereby improving quality film. This confinement strategy enables resulting Cs 0.05 MA FA 0.9 PbI 3 PSC devices (n‐i‐p) achieve an outstanding 25.58% (0.06 cm −2 ) one sun illumination. unencapsulated maintained over 96% their initial after continuous maximum point tracking 1200 h N 2 atmosphere. Importantly, PSCs demonstrated excellent even temperature ISOS‐L‐2 protocol, maintaining 90% peak at 85 °C 800 h.

The gas-releasing thermal decomposition processes of formamidinium tin triiodide perovskite (CN2H5SnI3, usually denoted as FASnI3 or, briefly, FASI) were investigated in order to obtain information on the temperature at which begins and nature gas species emitted under heating. Results thermogravimetry-differential analysis (TG-DTA), scanning calorimetry (TG-DSC), Knudsen effusion mass spectrometry (KEMS) experiments are presented. TG measurements showed that loss starts temperatures much lower than those lead-based corresponding compound FAPbI3, with incipient low 423 K. Unlike practically no residue is left T = 823 KEMS a measurable release SnI4(g) occurring from 318 K, pressure vapor pure SnI4, suggesting presence solid Sn-(IV) reduced activity. At higher (T > 390 K), SnI2(g) various coming organic portion, such formamidine, hydrogen iodide, ammonia, triazine, cyanide, observed. For first time, FASI was shown occur both inorganic (tin iodides) species, partial oxidation Sn-(II) significantly decreasing onset temperature. Finally, based scan rates, kinetic performed, using integral incremental isoconversional methods, derive parameters useful for lifetime prediction. Reasonable reaction time values achieve degree conversion (less 0.25) extrapolated typically involved operation photovoltaic devices (333 353 K).
