The surface treatment of solar panels with thin coating layer (s) would increase its potential to protect the reflectors and absorbents from corrosion, dirt and reflection loses . Self-cleaning coatings ease the removal of dust from the solar panels that in turn increases their energy conversion efficiency.
In this review, the current state of fabrication of solar panel coatings and their properties, including surface morphology, wettability, electrical conductivity and light transparency characteristics, are discussed.
It is well established that solar panel coatings must possess both antireflective and self-cleaning properties at the same time; otherwise, the purpose of coating solar modules will lose practical significance in great extent.
Dirt, temperature, wind speed, humidity, snowfall, and sand gales are significant environmental factors (covered in the “ Factors influencing the effectiveness of solar panels ” section) that substantially influence PV performance and may eventually lead to panel failure and module deterioration.
To improve the thickness uniformity, the dispensed solution volume is used to reduce the alteration of the advancing meniscus height along the coating direction and minimize the capillary flow with the appropriate substrate temperature. This study provides crucial insights toward the successful upscaling of perovskite solar cells by blade coating.
Coatings of solar panels to increase their self-cleaning property involve two types of films, such as, superhydrophilic and superhydrophobic films. Self-cleaning nano-films are being considered as potential coatings for improving the efficiency of PV modules.
