AI Technical Summary
Existing photovoltaic transparent self-cleaning antireflective layers suffer from rapid degradation of their superhydrophilicity and self-cleaning properties due to friction and wear under complex service environments, limiting their large-scale application in photovoltaic modules.
An organic cross-linked network is formed by polyvinyl alcohol and epoxy acrylate resin, combined with porous silica, alumina and tin dioxide nanoparticles, and a highly wear-resistant, superhydrophilic hydrogen bond network coating is formed through hydrogen bonding and physical cross-linking. The coating is then applied to a glass substrate and cured at high temperature.
The resulting coating withstood over 7500 revolutions under a 500g load Taber abrasion test, still maintaining excellent superhydrophilic and antireflective properties, significantly improving the photoelectric conversion efficiency and long-term stability of photovoltaic modules.
