Abstract

The invention discloses an organic solar cell acceptor material and a preparation method thereof, and the method comprises the following steps: step 1, reacting 9-(4-bromophenyl)-3,6-dibromocarbazolewith bis(pinacolato)diboron to generate an intermediate 1; step 2, carrying out Suzuki coupling on the intermediate 1 and 5-bromothieno[2,3-B] pyridine to generate an intermediate 2; step 3, reactingthe intermediate 2 with N-bromo-succinimide (NBS) to generate an intermediate 3, and further reacting the intermediate 3 with bis(pinacolato)diboron to generate an intermediate 4; step 4, performing Suzuki coupling on the intermediate 4 and substituted 5-bromo-2-furan formaldehyde to generate an intermediate 5; and step 5, carrying out a Knoevenagel condensation reaction on the intermediate 5 anda terminal group to generate a final product. The material not only can be used as an electron acceptor in an organic solar cell, but also can be used as an additive material for regulating and controlling a donor / acceptor interface of a ternary blending organic solar cell.

Description

technical field

[0001] The invention belongs to the field of solar cells, and in particular relates to an organic solar cell acceptor material and a preparation method thereof. Background technique

[0002] Traditional energy sources such as coal, oil, natural gas and other mineral energy are decreasing day by day, but the pollution of human's living environment and natural environment is becoming more and more serious. The demand for mineral energy is increasing day by day, while the earth's reserves are decreasing. In this context, a series of clean energy such as solar energy and wind energy, as an inexhaustible green new energy, has attracted more and more attention of scientists. How to replace traditional mineral energy with solar energy to protect the environment has become a research hotspot and the focus of industrial development in various countries. In the past few decades, due to the rapid development of inorganic semiconductor materials such as monocrystalline...
