Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a silicon-PEDOT:PSS hybrid solar cell and a preparation method thereof. Background technique [0002] Inorganic solar cells cannot be used on a large scale because of their high cost. Organic solar cells are expected to reduce the production cost of solar cells due to their advantages such as cheap materials, low annealing temperature, and simple fabrication process. However, the efficiency of organic solar cells is much lower than that of inorganic solar cells. Therefore, organic-inorganic hybrid solar cells based on inorganic and organic semiconductor materials are increasingly favored by people, which provides a production technology that can simplify manufacturing steps and reduce costs. Compared with organic materials, inorganic materials have the biggest advantage of high carrier mobility, which means that the material has a long mean free path and can effectively redu...
