Description

【Technical field】 [0001] The invention belongs to the field of new energy technology and solar cell material preparation technology, and in particular relates to a degradable photoelectric material for solar cells. 【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 can be freely utilized by human beings. 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 most extensive application research on solar energy. [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 sou...
