Application research of a new hydrophobic material improving photovoltaic power generation efficiency
This study experimentally investigates the application and optimization of perfluorobrominated quaternary ammonium salt as a novel hydrophobic material on the surface of photovoltaic panels.Initially,the hydrophobic materi-al was formulated at a specific ratio,and its antibacterial performance was evaluated.Utilizing a video optical contact angle measuring device,the contact angle of the coated photovoltaic glass panels was assessed,revealing that the water droplet contact angle exceeded 100°,indicating excellent hydrophobicity and self-cleaning properties of the material.Furthermore,the effects of the coating on photodegradation and Mohs hardness were measured,showing that photodeg-radation remained stable after coating,while Mohs hardness increased by one level.Spectrophotometric measurements of the film's transmittance and refractive index indicated a significant improvement in the light transmittance of the photovoltaic glass.Finally,comparative analysis of photovoltaic panels across different regions demonstrated that the application of the hydrophobic coating resulted in a maximum increase in power generation of 14.6%,while maintai-ning good energy efficiency.These findings suggest that perfluorobrominated quaternary ammonium salt has significant potential for enhancing photovoltaic efficiency and prolonging the lifespan of solar energy devices.
