Abstract Mixed tin‐lead perovskite solar cells can reach band gaps as low 1.2 eV, offering high theoretical efficiency and serving base materials for all‐perovskite tandem cells. However, instability defect densities at the interfaces, particularly buried surface, have limited performance improvements. In this work, we present modification of bottom interface with multifunctional hydroxylamine salts. These salts effectively coordinate different components, having critical influences in regulating crystallization process passivating defects varying nature. The surface reduced traps prevented formation excessive lead iodide, enhancing quality films. modified devices presented fill factors reaching 81 % efficiencies up to 23.8 %. unencapsulated maintained over 95 their initial after 2000 h shelf storage.

High defect concentrations at the interfaces are basis of charge extraction losses and instability in perovskite solar cells. Surface engineering with organic cations is a common practice to solve this issue. However, full implications counteranions these for device functioning often neglected. In work, we used 4-fluorophenethylammonium cation varying halide modification both methylammonium-free Pb-based n-i-p devices, observing significant differences among iodide, bromide, chloride. The treatment buried top resulted improved surface quality films largely carrier dynamics reduced nonradiative recombination. Consequently, optimal interface-modified cells surpassed 20% efficiency demonstrated remarkable operational stability. Our findings underscore potential comprehensive strategies advancing film quality, thereby facilitating their broader more successful applications.

Abstract Metal halide perovskite‐based devices can exhibit exceptional optoelectronic performance at relatively high defect densities, a phenomenon commonly referred to as tolerance, which is one of the most important features metal perovskites (MHPs). Defect tolerance previously thought be static property, determined solely by composition and manufacturing process. However, recent studies have shown that MHPs dynamic vary over time. For example, power conversion efficiency MHPs‐based solar cells has been found improve significantly under continuous illumination. Although this unique self‐optimization behavior MHPs, it seriously affect stability output in real‐world operating conditions. In view this, extensive research conducted, but physical mechanism photoinduced (DDT) remained inconclusive, both mechanisms experimental phenomena continue subjects controversy. Therefore, timely summarization on related DDT urgently needed. review, systematic overview first provided phenomena, characteristics, influencing factors DDT. Following that, proposed for are summarized, with focus carrier‐defect carrier‐lattice interactions. Finally, current challenges faced summarized an outlook future developments provided. This review aims offer comprehensive understanding enhance cells, thereby facilitating advancement commercialization these technologies.
