The present invention relates to a method for preparing a coating liquid for increasing the transmittance of glass used in the manufacture of a solar cell module when coated on said glass, and to a coating solution composition prepared by the method. In the prior art, in order to increase light transmittance, high and low refractive index layers are alternately stacked, an antireflection optical catalyst coating is implemented, or a porous alkoxysilane structure is used. However, these methods are difficult to employ because of the drawbacks thereof, such as the difficulty in precision stacking, high costs, or the limited storage stability of the coating liquid. Therefore, the present invention is proposed to overcome such drawbacks by filling and arranging inorganic particles, the size of which is several tens to several hundreds of nanometers, such that the inorganic particles form an array structure similar to a porous structure in order to exhibit the property of a porous structure of improving transmittance, while improving hardness due to the mechanical features of the filled inorganic particles. |
