The reaction mechanism and process of the method are introduced in the paper. The solar photovoltaic/thermal transfer principle, classification of solar thin films and the latest research have been introduced emphatically, which prove that solar thin films prepared by sol-gel has a high conversion rate. And the development trends and application prospects of the solar thin films prepared by sol-gel method are pointed out, too.%介绍了溶胶-凝胶法的反应机理、工艺过程,着重介绍了太阳能光电/光热转换的原理、薄膜的分类以及最新研究现状,指出采用溶胶-凝胶法可获得高效率太阳能薄膜,并展望了溶胶-凝胶法在太阳能薄膜制备方面的发展趋势及应用前景.
