Description

technical field [0001] The invention belongs to the field of solar cells, and in particular relates to a solar cell with a double-layer perovskite film structure and a preparation method thereof. Background technique [0002] With the depletion of fossil fuels, the development of clean energy is an inevitable means for human beings to achieve sustainable development. Solar cells provide inexhaustible clean energy by converting a steady stream of solar energy into electrical energy, which is an important countermeasure for sustainable development. [0003] At present, the commercialized batteries are mainly silicon solar cells and their compound solar cells. The high cost of materials and preparation restricts its development. Therefore, new solar cells with low cost and simple preparation process have become the focus of competing research in various countries. . In particular, the cost of perovskite solar cells is low and the preparation process is simple. In 2009, Miyasa...
