METHOD FOR PREPARING A COATING SOLUTION FOR INCREASING THE LIGHT TRANSMITTANCE OF SOLAR CELL MODULE GLASS, AND COATING SOLUTION COMPOSITION PREPARED BY THE METHOD

摘要

Provided are an method for producing a coating solution with which glass used for the production of solar collector modules is coated to enhance the optical transmittance, and a coating composition produced by the same. According to the prior art, there is a method of alternately stacking a high refractive index layer and a low refractive index layer on each other, coating a film with a photocatalyst for the anti-reflection of films, or using alkoxysilane having a porous structure, in order to increase the transmission of light. However, the prior-art method has problems in that it is difficult to precisely stack the high and low refractive index layers, the production cost is high, and the storage stability of the coating solution is restricted, which makes it difficult to use the prior-art method. However, the present invention is designed to solve such drawbacks of the prior art, the production method and coating composition may be useful to arrange the inorganic particles with a diameter of several ten nanometers to several hundred nanometers so that the inorganic nanoparticles can have a similar array to the porous structure, thereby improving the mechanical property (for example, hardness) of the filler while enhancing the transmittance of the porous structure.
