Abstract

The invention relates to a preparation method of an active layer of a polymer solar cell, comprising the steps of dissolving donor material, receptor material and auxiliaries in an organic solvent toobtain an active layer solution, then spin-coating the active layer solution on substrate material for three times to obtain active layer films, annealing the substrate material with the active layerfilms, and storing away from light in a sealed container. In the preparation method, the rotating speed and time of a spin coater are adjusted consecutively for three times, wherein a film I is prepared at a low speed within short time, a film II is prepared at a medium speed within long time, and a film III is prepared at a high speed within long time, so that not only is the nonuniformity of theactive layer films caused by the nonuniform surface of the substrate avoided and the adhesion between the active layer and the substrate improved, but also the thickness of the active layer requiredby the polymer solar cell and the effective light absorption are guaranteed, and the problems of scattering distribution and poor adhesion between the active layer and the substrate caused by single spinning coating of an active layer film are avoided.

Description

technical field [0001] The invention relates to the technical field of solar cells in new energy sources, in particular to a method for preparing an active layer of a polymer solar cell that improves the adhesion between an active layer and a substrate and has a uniform thin film of the active layer. Background technique [0002] In today's society, the rapid economic development has brought serious problems such as energy crisis and global warming. The development and utilization of renewable clean energy has attracted widespread attention from all over the world. Different from traditional energy sources such as coal, oil, and natural gas, solar energy is a green, clean, and renewable energy source that is inexhaustible and has the potential to become an important part of supply.
