A fluorine-containing hydrophobic Lewis acid is employed as an effective dopant for PTAA to replace state-of-the-art Li-TFSI/<italic>t</italic>-BP in PSCs.
Abstract The development of a robust quasi-ohmic contact with minimal resistance, good stability and cost-effectiveness is crucial for perovskite solar cells. We introduce generic approach featuring Lewis-acid layer sandwiched between dopant-free semicrystalline polymer metal electrode in cells, resulting an ideal even at elevated temperature up to 85 °C. solubility Lewis acid alcohol facilitates nondestructive solution processing on top polymer, which boosts hole injection from into by two...
Suppressing deep-level defects at the perovskite bulk and surface is indispensable for reducing non-radiative recombination losses improving efficiency stability of solar cells (PSCs). In this study, two Lewis bases based on chalcogen-thiophene (n-Bu4S) selenophene (n-Bu4Se) having tetra-pyridine as bridge are developed to passivate in film. The uncoordinated Pb2+ iodine vacancy can interact with chalcogen-concave group pyridine through formation acid-base adduct, particularly both be...
Abstract Reduced‐dimensional (2D or quasi‐2D) perovskites have recently attracted considerable interest due to their superior long‐term stability. The nature of the intercalating cations plays a key role in determining physicochemical properties and stability quasi‐2D perovskites.

Animals such as chameleons possess a natural ability to adjust their skin color preventive measure deter any potential threat and self-heal damaged tissues. Inspired by this, we present here copolymer film possessing biomimetic properties that simultaneously integrates electrochromic triphenylamine self-healing Diels-Alder groups. The flexible stretchable acts like chameleon skin, which exhibits significant variation also possesses excellent properties. These remarkable features make it...
The tactics of ion doping in metal oxide is normally used to improve the film quality, achieve an appropriate energy band, and enhance carrier mobility.
