Yingcai® super-hydrophilic photovoltaic self-cleaning photocatalytic nano coating is a high-performance protective material. Through nano technology, it builds a super-hydrophilic structure on the glass surface, enabling rainwater self-cleaning, anti-static dust resistance, light transmission enhancement and anti-reflection performance.
The coating has a pencil hardness above 5H and excellent wear resistance. With weather resistance lasting more than 5 years, it can significantly reduce cleaning frequency and operation and maintenance costs. It is suitable for various complex environments and can improve module power generation efficiency by 15% to 25% or more, helping photovoltaic power stations achieve long-term performance gains.
Product Features
-
Superhydrophilic PerformanceA water contact angle below 10° allows rainwater to spread completely across the surface, helping prevent beading and water-mark residue.
-
Photocatalytic CleaningUnder natural light, the photocatalytic surface helps break down oily films, bird droppings and other organic deposits.
-
Dust Reduction and Energy-Yield SupportReduces dust adhesion by up to 80% and supports a stable 3%–8% increase in PV energy yield under suitable operating conditions.
-
Weather-Resistant ProtectionResists acid rain and salt spray while helping protect the glass substrate from corrosion caused by saline and alkaline dust.

Higher Light Transmission for Improved Energy Yield
The coating uses advanced anti-reflective technology to reduce reflection losses at the PV glass surface and improve light transmission. More sunlight can reach the solar cells, supporting higher module output and better plant returns under the same irradiance conditions.
Superhydrophilic Self-Cleaning and Dust Control
Photocatalytic activity and superhydrophilicity allow water to form a continuous film across the glass. Rainwater or condensation spreads quickly and flows evenly, carrying away dust, bird droppings and other contaminants. This rain-assisted cleaning effect reduces manual washing demand and helps modules maintain dependable energy production.
Photocatalytic Decomposition of Organic Contaminants
-
When exposed to sunlight, particularly ultraviolet light, the nano materials initiate a photocatalytic reaction that generates highly oxidative active species. These help decompose oily films, plant residues and other organic contaminants into carbon dioxide and water, reducing contamination-related hot spots and energy losses.
Durable, Wear-Resistant Protection for PV Glass
-
In addition to its functional surface properties, the coating provides strong hardness and adhesion to PV glass. It forms a durable barrier against windblown sand and natural ageing, helping delay corrosion and wear, preserve light transmission and extend the useful life of solar modules.
