| Outline of Final Research Achievements |
By silica nanoparticles coating on the solar panel surface, tiny roughness are made on the surface to reduce the reflection of sunlight and increase the transmitted light. In addition, adhesion to dust can be reduced due to irregularities on the surface, and improvement in power generation efficiency due to antifouling effect of the solar panel can be expected.
The antireflection effect depends on the surface roughness of the nanoparticle layer and is greatly affected by the coating method. As the experimental results, it was possible to improve the power generation efficiency by decreasing the reflectance by placing the brush on the substrate surface and spraying it. This method can be easily used for existing solar panels and can be put into practical use.
