Abstract Perovskite solar cells (PSCs) have made unprecedented progress in improving power conversion efficiency the past decade, and they are considered as one of most promising photovoltaic technologies. However, commercialization PSCs still faces significant challenges, such stability issue toxicity lead. Recently, pursuing ways to alleviate lead has emerged an attractive research direction community PSCs. In this review, discussion is on impact leakage from perovskites environment,...
Polymorphism, the ability of same substance to crystallize in more than one crystal structure, is a common phenomenon organic crystals, influencing physicochemical properties solid materials many important fields (foods, dyes and pigments, high energic materials, pharmaceuticals, etc.). The utilization various polymorph discovery methods could increase possibility finding polymorphs with desired properties, achieving an optimal performance final product. Recently, there has been steady...
All-inorganic CsPbI2Br with outstanding thermal stability and excellent photoelectric properties is considered as a promising candidate for photovoltaic applications. However, the efficiency of perovskite solar cells (PSCs) still much lower than that their organic–inorganic hybrid counterparts or CsPbI3-based devices.

Through systematic research, it found PBSA...
SnO 2 ‐based planar perovskite solar cells (PSCs) have attracted extensive attention owing to their simple structure and low‐temperature processing. However, the imperfect interface contact caused by surface defects energy‐level mismatches greatly hinder further improvement of efficiency stability PSC. Herein, a multifunctional interfacial crosslinking agent D‐penicillamine (DPM) is introduced improve between upper perovskite. Through systematical analysis, it found that DPM used modify can...
Abstract 2D bismuth‐based perovskites have attention as a potentially transformative technology in optoelectronics due to their exceptional non‐toxic and environmentally friendly properties. However, practical applications are hindered by the low luminous efficiency caused self‐trapped excitons (STEs) under normal environmental conditions.

Abstract In n–i–p structured perovskite solar cells (PSCs), the electron transport layer (ETL)/perovskite interfaces greatly influence power conversion efficiency (PCE) and stability of devices. recent years, more works have successfully prepared PSCs with excellent performance after employing tin dioxide (SnO 2 ) as ETL. However, oxygen vacancies hydroxyl groups on SnO ETLs produced during preparation can easily induce defects at film surface injure above film. Herein, a multifunctional...
The effect of In-doping on the quantum information entropy hydrogenic impurity states in InxGa1-xN dot has been studied for first time. By exploring Shannon position space (Sr), momentum-space (Sp) and sum St, we find some novel interesting phenomenon.
