Abstract

The invention provides a production method for a large-area organic polymer solar cell. The method includes the following steps: (a) an anode is formed on a flexible substrate by an etching process; (b) the flexible substrate with the anode is mounted on a damped unreeling mechanism in front of a coating system, and after three times of coating in the three continuous coating processes of the coating system, a hole transport layer, an organic active layer and a cathode are sequentially formed on the anode of the flexible substrate, so that an organic solar cell is formed; (c) the organic solar cell is cut, connected with electrode pins and packaged to form a finished product. The production method can be adopted to produce large-area organic solar cells; moreover, the production time can be saved as well, and the efficiency can be increased; the waste of solution can be reduced, and the cost can be saved.

Description

technical field [0001] The invention relates to a method for preparing a solar cell, in particular to a method for preparing a solution-prepared large-area organic polymer solar cell. Background technique [0002] With the rapid development of the world economy, the problem of energy shortage has gradually emerged. People gradually realized that fossil energy may be exhausted one day, so they began to look for possible alternative energy sources. Solar energy is widely distributed, abundant and does not pollute the environment. Therefore, the conversion and utilization of solar energy has been highly valued by various countries. At present, the most widely used solar cells are mainly inorganic solar cells of monocrystalline silicon, polycrystalline silicon and amorphous silicon series. However, the processing procedures of inorganic solar cells are very complicated, demanding on the environment, and the cost is too high. The battery shows its advantages in these respects. ...
