Problems solved by technology

[0002] The solar panel is composed of aluminum frame, TPT film, EVA film, solar battery string and solar glass. The solar glass plate plays the role of encapsulation, which can improve the impact resistance of the component and seal the component to improve the waterproof of the solar panel. At present, the mainstream product of solar glass panels is low-iron toughened patterned glass. The refractive index of this type of glass is not high, and the glass panel is prone to blackening after conduction, resulting in a decrease in the amount of visible light passing through the glass panel, affecting The efficiency of photovoltaic power generation
[0003] In the current solar glass manufacturing process, such as a photovoltaic glass formula disclosed in Chinese patent CN102617034B and its application, Sb is added to the raw material 2 o 3 and Na 2 o 3 , low-temperature melting stage, Sb 3+ in Na 2 o 3 Oxidized to Sb under the action of 5 + , high temperature melting stage, Sb 5+ Make Fe 2+ Oxidized to Fe 3+ , so that the coloring ability of the glass is reduced, and the light transmittance is increased. However, due to the existence of tiny bubbles in the solar glass, only by reducing Fe 2+ The content of the solar glass has a limited improvement in the light transmittance
