Starburst non-fullerene organic small molecule receptor material containing pyrene and perylene diimide and preparation method of starburst non-fullerene organic small molecule receptor material

Abstract

The invention discloses a starburst non-fullerene organic small molecule receptor material containing pyrene and perylene diimide and a preparation method of the starburst non-fullerene organic smallmolecule receptor material. The non-fullerene organic small molecule receptor material is bridged with condensed nucleus pyrene and perylene bisimide units through triple bonds, the obtained materialhas good thermal stability, raw materials are common and easy to obtain and can be purified through recrystallization, and the production cost is low; and the starburst non-fullerene organic small molecule receptor material is applied to a polymer solar cell, the effect with the energy conversion efficiency being 6-8% can be achieved under the condition of an optimizing device, the starburst non-fullerene organic small molecule receptor material serves as a third component to be added into a ternary solar cell active layer, the density of a short-circuit current of the ternary solar cell active layer can be remarkably increased, the effect with the energy conversion efficiency being 8-11% can be achieved, and certain practical application value is achieved.

Description

Technical field

[0001] The invention relates to a non-fullerene organic small molecule receptor material for polymer solar cells and a preparation method thereof, in particular to a star-shaped non-fullerene organic small molecule receptor material containing pyrene and perylene diimide And its preparation method. Background technique

[0002] Traditional fossil fuels are non-renewable, economic development has soared energy demand, changes in energy consumption structure, and the uncontrolled exploitation and utilization of fossil fuels have led to several energy crises that have erupted worldwide, which has brought unprecedented impact to the living environment of mankind. Pressures and challenges. In response to the increasingly serious energy problem, research and development of new clean and renewable energy sources (solar energy, wind energy, tidal energy, etc.) have become a major issue facing mankind. As one of the most abundant and clean energy sources, solar energy ha...
