摘　　要：众所周知,能源驱动城市发展,然而随着传统能源日渐枯竭以及全球环境污染逐日加剧,人类迫切需要寻找新型可再生能源以驱动城市发展。因此,发展可再生能源已成为我国能源结构转型和缓解气候恶化的关键途径。科学研究表明,太阳能发电是一种清洁可再生的能源利用方案,具有“取之不尽,用之无竭”的优点。目前已商用化的晶体硅太阳能电池的光电转化效率最高,但受材料纯度和制备工艺的限制,晶体硅太阳能电池很难在提高光电转化效率的同时降低生产成本。于是,硅基薄膜太阳能电池的问世无疑是一道曙光——薄膜太阳能电池只需几微米的吸光层就能实现高效率光电转换,可以在降低生产成本的同时提高光电转化效率,具有生产成本低、硅材消耗少、光电转换效率高的无可比拟优势。As we all know,energy drives urban development.However,with the depletion of traditional energy sources and the increasing global environmental pollution,mankind urgently needs to find new renewable energy sources to drive urban development.Therefore,the development of renewable energy has become a key strategy to transform China's energy structure and alleviate climate deterioration.Scientific research shows that solar power is a clean and renewable energy utilization program.At present,the commercialized crystalline silicon solar cells have the highest photoelectric conversion efficiency,but due to the limitation of material purity and preparation technology,it is difficult for crystalline silicon solar cells to improve the photoelectric conversion efficiency while reducing production costs.Therefore,the advent of silicon-based thin-film solar cells is undoubtedly a dawn for thin-film solar cells can achieve high-efficiency photoelectric conversion with only a few micrometers of light-absorbing layer,which can reduce production costs while improving photoelectric conversion efficiency,with the unparalleled advantages of low production costs,little silicon consumption,and high photoelectric conversion efficiency.
