Features are: simple technique, stale performance, theoretical service life of more than 20 years.

Description

technical field [0001] The invention relates to a solar cell, in particular to a soft base thin-film solar cell and a preparation method. Background technique [0002] As the focus of solving the energy crisis and environmental pollution, solar cells have been paid more and more attention by governments of various countries. There is a big gap between the development and research of solar power in my country and developed countries. Research and development of low-cost, high-efficiency, easy-to-manufacture, install, and use thin-film solar cells with independent intellectual property rights is one of the urgent issues faced by Chinese scientific and technological workers. [0003] As far as several solar cells are currently being applied and researched, the conversion efficiency of monocrystalline silicon solar cells has reached 24%, basically reaching the limit. Due to the high manufacturing cost and the fact that silicon materials are mainly derived from off-grade semico...
