Description

technical field [0001] The invention relates to the field of material technology, in particular to a novel organosilicon complex and a preparation method thereof. Background technique [0002] With the increasing scarcity of traditional energy sources, the global development and utilization of new energy sources has increasingly become the focus of worldwide attention. As a new energy source, solar energy has the characteristics of inexhaustible, inexhaustible, pollution-free, and pollution-free. It has attracted global attention and realized the industrialization of energy transformation. [0003] A solar cell is a device that uses sunlight to directly generate electricity, and has been widely used. An important component in solar cells is the photovoltaic glass. In order to further improve the photoelectric conversion efficiency of solar cells, an anti-reflection coating is generally used on the surface of photovoltaic glass to reduce the reflection loss of incident ligh...
