Description

technical field [0001] The invention belongs to the technical field of solar cell materials, and in particular relates to a wide-spectrum solar cell material and a preparation method thereof. Background technique [0002] The shortage of energy has seriously affected people's life and restricted the development of society. Abundant solar energy is an important clean energy, an inexhaustible, inexhaustible, pollution-free, cheap energy that human beings can use freely. After the first oil crisis, countries competed to carry out research on the application of clean and renewable energy such as solar energy, water energy, and wind energy, especially the application of solar energy is the most extensive. [0003] As a kind of green energy, solar energy has no pollution to the environment, and its source is simple, so it can be said that it is inexhaustible within the life span of human beings. Solar energy is not only a one-time energy source, but also a clean energy sourc...
