Recombination in Perovskite Solar Cells: Significance of

nhận giá

Trapassisted recombination, despite being lower as compared with traditional inorganic solar cells, is still the dominant recombination mechanism in perovskite solar cells (PSCs) and limits their efficiency. We investigate the attributes of the primary trapassisted recombination channels (grain boundaries and interfaces) and their correlation to defect ions in PSCs.

A perovskite is any material with the same type of crystal structure as calcium titanium oxide (CaTiO 3), known as the perovskite structure, or XII A 2+VI B 4+ X 2− 3 with the oxygen in the edge centers. Perovskites take their name from the mineral, which was first discovered in the Ural mountains of Russia by Gustav Rose in 1839 and is named after Russian mineralogist L. A. Perovski (1792
