Description

technical field [0001] The invention belongs to the technical field of photoelectric conversion devices, and in particular relates to a single-layer organic solar cell and a preparation method thereof. Background technique [0002] A solar cell is a photovoltaic device that converts light energy into electricity. Since Bell Laboratories reported inorganic solar cells with an efficiency of 4% in 1954, solar cells have developed rapidly in the past half a century, and a "green energy revolution" has been set off worldwide. After the 1990s, photovoltaic devices such as gallium arsenide and cadmium telluride have been developed in the family of inorganic solar cells. However, until today, the high cost is the primary problem limiting the large-scale application of inorganic semiconductor solar cells. However, the cost problem is mainly caused by the inorganic materials themselves, so only the real low-cost green energy is an effective way to solve the energy problem. [0003]...
