Abstract
The invention belongs to the technical field of organic functional materials, and relates to a perylene diimide electron transport material, a synthesis method thereof, and application of the perylenediimide electron transport material in a trans-planar perovskite solar cell. According to the invention, a phenothiazine dioxide group is used as a core structure, a perylene diimide group is connected to 3- and 7- substitution sites of a phenothiazine dioxide structure unit, and perylene diimide electron transport materials with different torsion structure configurations are constructed by introducing different peripheral groups and regulating and controlling the spatial stereoconfiguration of molecules. The perylene diimide electron transport material provided by the invention has the advantages of stable conditions, low cost, high electron mobility and the like. Compared with a trans-planar perovskite solar cell based on a fullerene electron transport material, the cell based on the electron transport material has no relaxation phenomenon under a working condition. In addition, the manufacturing cost is lower, the photoelectric conversion efficiency is higher, the stability is better, and large-scale commercial production is promoted.
Description
technical field [0001] The invention belongs to the technical field of organic functional materials, and relates to a perylene diimide electron transport material, a synthesis method thereof, and an application in trans planar perovskite solar cells. Background technique [0002] Solar cells convert sunlight directly into electricity, which is considered to be a renewable and clean energy technology that can effectively alleviate the global energy crisis and environmental pollution problems. Since the advent of all-solid-state organic-inorganic hybrid perovskite solar cells (Perovskite Solar Cells, PSCs) in 2012, its highest photoelectric conversion efficiency has reached 25.2% in just a few years. Because perovskite materials have the advantages of narrow energy band gap, high extinction coefficient, long carrier diffusion length, long carrier lifetime and high carrier mobility, and the device preparation process is simple and low cost, so perovskite solar energy The batte...
