Description

technical field [0001] This application belongs to the field of optoelectronics. In particular, the present application relates to solar cells and methods of making them. Background technique [0002] In today's society, the continuous consumption of fossil energy makes human beings face the crisis of energy shortage, and the development of renewable energy is imminent. As a green, non-polluting, inexhaustible clean energy, solar energy can meet the ever-increasing energy demand of human beings. Therefore, the utilization of solar energy has attracted worldwide attention. Compared with inorganic silicon solar cells, organic solar cells have become one of the most potential photovoltaic devices due to their advantages of low cost, light weight, solution processing, flexible devices, and large-area printing preparation. [0003] After recent years of development, the energy conversion efficiency of single-junction organic solar cells has exceeded 14%. However, the absorptio...
