This is an introduction to the verification test of the light transmittance improvement effect of the inorganic antifouling coating agent "Excel Pure" using a photometer. A PET film coated with Excel Pure on one side was placed between the light source and the sensor, and the illuminance was measured via the uncoated surface and the coated surface, confirming the change in illuminance. The illuminance measurement value via the uncoated surface was 337 Lux, while the value via the coated surface was 354 Lux, showing an increase of approximately 4.8%. [Test Method] - The illuminance meter sensor was installed directly under the LED reading light source to measure the illuminance of the reading light. - A PET film coated with Excel Pure on one side was placed between the light source and the sensor, measuring the illuminance via the uncoated surface and the coated surface to confirm the change in illuminance.

The glass substrate of solar panels faces the issue of decreased power generation efficiency due to the accumulation of rain, sand, dust, and other factors over time. In recent years, foldable film substrate-type (perovskite) solar cells have also been developed, but maintaining and improving power generation efficiency remains important. "Excel Pure," developed by Central Automotive Industry, suppresses light reflection and enhances transmittance through a low-refractive-index coating. As a result, it efficiently captures sunlight, leading to an increase in power generation efficiency, which has received positive feedback. In addition to improving light transmittance, it also offers anti-soiling effects due to hydrophilicity and static electricity prevention, and can be applied to glass, resin, and film substrates. [Application Examples] ■ Increase in power generation efficiency of solar panels ■ Improvement of lens image quality ■ Enhancement of photoelectric sensor sensitivity ■ Increase in light output of lighting fixtures We will also be exhibiting at the "Functional Film Exhibition 2025" held at the Osaka Industrial Creation Center. We look forward to your visit. *For more details, please refer to the PDF materials or feel free to contact us.
