Abstract |
In this study, we suggest a functional coatings to improve the durability and anti-pollution properties of solar cell modules. Anti-pollution functional coating was employed on the glass substrate for the PV module. After coating with a brushing technique on a glass substrate, a hot air fan of approximately 200°C was operated for 2 minutes. Using the method which the coating and annealing process was applied, it was performed 2 ~ 3 times every 5 minute intervals. Samples that completed by all the coating and annealing processes were installed outdoors to conduct the durability testing. In order to investigate the change in durability, characteristics such as light transmittance and contact angle were analyzed. The contact angle confirmed the improved hydrophilic property of glass with the deionized water of 5 μL, resulting in the easy cleaning of the PV module cover glass and light transmittance was surveyed using a UV-visible spectroscopy to analyze changes in its properties according to the outdoor environment. |
