Overcoming Uncontrolled Nucleation and Cesium Salt Solubility Limits in Scalable Perovskite Deposition through All-Inorganic Perovskite Nanocrystal Seeding

Abstract Optoelectronic performance, defect density, and thin-film morphology of solution-processable lead halide perovskites are highly dependent on nucleation and growth conditions during processing. Additionally, Cs+ incorporation into the lattice can have benign effects on th...

Disentangling surface and bulk properties of Ta3N5 photoanodes

Abstract Understanding how material and defect characteristics govern photoelectrochemical performance is essential for developing efficient and stable photoelectrodes. Although bulk properties are often emphasized, surfaces and interfaces can equally determine activity and stabi...
