Description

technical field [0001] The invention relates to a polymer solar cell and a preparation method thereof. Background technique [0002] With the aggravation of the global energy crisis and environmental pollution, solar cells that convert solar energy, a clean renewable energy, into electrical energy have received great attention from countries all over the world. Among all kinds of solar cells, inorganic semiconductor solar cells occupy most of the current solar cell market due to their high photoelectric conversion efficiency and mature technology. However, inorganic semiconductor solar cells have many disadvantages, such as high cost, high energy consumption, complicated manufacturing process, non-flexibility, heavy weight, and difficulty in large-scale preparation, which limit their large-scale application in many fields. [0003] Compared with traditional inorganic solar cells, flexible polymer solar cells are low in cost, simple to manufacture, easy to manufacture in lar...
