Abstract

The invention discloses an organic solar cell and a making method thereof. The making method comprises the following steps of: cleaning and drying a substrate which takes a transparent material as a base plate on which a strip-type transparent conducting oxide film is etched for later use; making a cathode-modified layer with electronic transmission performance, a photoactive layer formed by mixing an electronic donor material and an electronic acceptance material, an anode-modified layer with hole transport performance and an anode layer formed by solidifying conductive paste on the transparent conducting oxide film, which serves as a cathode layer, on the substrate, by adopting a wet method; and annealing to obtain the organic solar cell. By the making method for the organic solar cell,the shortcomings of complex process, long making time, high cost, high energy consumption and the like which are caused by vacuum evaporation can be overcome; the making efficiency of the organic solar cells is improved; the energy consumption and cost are reduced; and the method is applicable for industrialized production of organic solar cells.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a method for preparing an organic solar cell and an organic solar cell prepared by the method. Background technique [0002] With the rapid development of the global economy, the consumption of energy has increased sharply. The huge use of fossil fuels has not only caused the depletion of non-renewable energy such as coal, oil, and natural gas, threatening the energy security of human society, but also a large amount of carbon dioxide emissions. It has caused increasingly serious social and environmental problems. In this situation, there is an urgent need to develop and utilize clean energy with both economic performance and high performance. Among them, solar energy is regarded as one of the available, most promising, and renewable energy sources, and has attracted widespread attention. [0003] Solar energy utilization schemes mainly include photothermal and photovoltaic...
