At this stage of their development, the key issues concern how to achieve further ... Lead halide perovskites can adopt an ABX 3 structure, where the A site is typically composed of organic methylammonium (MA), formamidinium (FA), or inorganic …
Näe rohkem >>Perovskites have a general formula of ABX 3, where smaller transition metal ions on the B site reside in corner-sharing octahedra of X anions, and larger A-site cations have 12-fold coordination with X ().Calcium titanate (CaTiO 3) was the first mineral discovered in this structural family, which was named "perovskite" after the Russian mineralogist Lev …
Näe rohkem >>We demonstrate a monolithic perovskite/CIGS tandem solar cell with a certified power conversion efficiency (PCE) of 24.2%. The tandem solar cell still exhibits photocurrent mismatch between the subcells; thus optical simulations are used to determine the optimal device stack. Results reveal a high optical potential with the optimized device reaching a …
Näe rohkem >>We began by considering candidate molecules that contain a benzene ring because its flat structure is expected to lie parallel to a surface compared with the case of linear-chain ligands ().To enable strong binding with perovskite surfaces, we considered both –PO 3 2− and –SO 3 − functional groups, each of which is reported to coordinate strongly with Pb …
