Abstract: There is provided a method for producing a coating solution used on glass for solar collector modules to enhance optical transmittance, comprising: preparing a sol of particles having a diameter of about ten nanometers to about several hundred nanometers by adding a coagulation-inducing agent to a coating solution to induce coagulation of the coating solution by the sol-gel reaction, wherein the coagulation-inducing agent reacts with aluminum alkoxide.
