Abstract

The invention discloses high-transparency solar photovoltaic glass which comprises a glass body, wherein a coating film is arranged on the surface of the glass body, and is formed by a film coating solution; the film coating solution comprises the following components in parts by volume: a silicon dioxide solution, a titanium dioxide solution, triethanolamine, polyethylene glycol, ethylene glycol and aluminum oxide. The film coating solution is used for preparing an inorganic hybrid membrane layer with a porous structure by using nanometer silicon dioxide as a basic system, main components of the nanometer silicon dioxide material is consistent with main components of the photovoltaic glass, and the binding performance of nanometer silicon dioxide material and the glass body is good; silicon dioxide is very stable at normal temperature, and has better acid and alkaline resistance and high-temperature resistance.

Description

technical field [0001] The invention relates to a solar photovoltaic glass, in particular to a solar photovoltaic glass with high light transmittance, and belongs 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 of the existing methods to solve the photoelectri...
