Abstract

The invention discloses a high transmittance film coating liquid used for preparing solar photovoltaic glass. The high transmittance film coating liquid used for preparing the solar photovoltaic glass is composed of a silicon dioxide solution, a titanium dioxide solution, triethanolamine, polyethylene glycol, ethylene glycol and aluminium oxide. The high transmittance film coating liquid used for preparing the solar photovoltaic glass adopts nano silica as a basic system for preparing an inorganic hybrid membrane layer with a porous structure, the nano silica material is consistent with main ingredients of photovoltaic glass, bonding property between the nano silica material and a glass body is good, and silica is very stable at normal temperature and has good acid and alkali resistance and high temperature resistance.

Description

technical field [0001] The invention relates to a coating solution, in particular to a coating solution with high transmittance for preparing solar photovoltaic glass and a preparation method thereof, belonging to the technical field of solar photovoltaic preparation. Background technique [0002] At present, the well-known photoelectric conversion of solar energy depends on the silicon wafer in the solar cell module, which has a good light absorption effect. With the continuous improvement of solar cell modules, the photoelectric conversion rate of the silicon wafer in the solar cell module is The current manufacturing level has reached the limit, and it has become a difficult problem to improve the photoelectric conversion rate of solar cells. At the same time, since the workplaces of solar cells are mostly installed outdoors or in deserts with harsh environments, the surface of solar cell modules is easy to get dirty, and it is difficult to clean after being dirty. One o...
