Abstract Tin‐based perovskites have exhibited high potential for efficient photovoltaics application due to their outstanding optoelectrical properties. However, the extremely undesired instabilities significantly hinders development and further commercialization process. A novel tin‐based reduced‐dimensional (quasi‐2D) is reported here by using 5‐ammoniumvaleric acid (5‐AVA + ) as organic spacer. It demonstrated that introducing appropriate amount of ammonium chloride (NH 4 Cl) additive,...
Perovskite solar cells (PSCs) that incorporate both two-dimensional (2D) and three-dimensional (3D) phases possess the potential to combine high stability of 2D PSCs with superior efficiency 3D PSCs. Here, we demonstrated in situ phase reconstruction 2D/3D perovskites using a perovskite single-crystal-assisted method. A gradient distribution RP was formed after spin-coating solution Ruddlesden–Popper (RP) single crystal, (DFP)2PbI4, onto surface, followed by thermal annealing. The resulting...
The unprecedented development of perovskite solar cells (PSCs) makes them one the most promising candidates for terawatt-scale green energy production with low cost. However, high boiling point solvents during solution-processed film deposition cause anisotropic crystal growth and toxic solvent vapor high-throughput manufacturing. Here, a dual-component consisting isopropyl acetate acetonitrile is proposed to form volatile precursor, which can realize high-quality thin by intermediate phase...
The conjugated organic semiconductor spacers have drawn wide attention in two-dimensional (2D) perovskites and formamidinium (FA) has been widely used as A-site cation high-performance 3D perovskite solar cells (PSCs). However, the FA-based rarely investigated 2D Ruddlesden-Popper (RP) perovskites. Here, we developed two containing thieno[3,2-b]thiophene (TT) 2,2'-bithiophene (BT) units, namely TTFA BTFA, respectively, for RP PSCs. nucleation crystallization kinetics of TTFA-Pb BTFA-Pb from...
Abstract Organic–inorganic halide perovskite solar cells (PSCs) have attracted significant attention in photovoltaic research, owing to their superior optoelectronic properties and cost‐effective manufacturing techniques. However, the unbalanced charge carrier diffusion length materials leads recombination of photogenerated electrons holes. The inefficient collecting process severely affects power conversion efficiency (PCE) PSCs. Herein, a solution‐processed SnO 2 array electron transport...
Abstract Metal halide perovskite solar cells (PSCs) have emerged as one of the most promising candidates for next‐generation photovoltaic technologies. However, films deposited by blade‐coating usually exhibit inferior film morphology compared to those fabricated spin‐coating, which hinders power conversion efficiency (PCE) and stability scalable modules (PSMs). Herein, ellipsoidal colloids are tailored in precursor solution incorporating polymer additives. Compared unregulated spherical...
A single-layer graphene film was grown on copper foil by chemical vapor deposition and transferred onto a silicon-pillar-array (SPA) substrate to make Schottky junction solar cell.

Li‐TFSI/t‐BP is the most widely utilized p‐dopant for hole‐transporting materials (HTMs) in state‐of‐the‐art perovskite solar cells (PSCs). However, its nonuniformity of doping, along with hygroscopicity and migration dopants, results devices that exhibit limited stability performance. This study reports use a spherical anion p‐dopant, regulated by radius shape, as an alternative to linear TFSI− anion. The theoretical experimental reveal significantly increases doping HTMs due enhanced...
