Chinese PV manufacturers have achieved a 20% efficiency gain using novel polysilazane (PSZ) coatings on solar glass. This material forms a nanoscale protective film at high temperatures, reducing surface light reflection by 90% while providing exceptional weather resistance against sand erosion. At a Northwest China solar farm, coated panels demonstrated over 20% higher daily power generation with 5+ years extended lifespan.
As carbon neutrality goals advance, PSZ coating costs have dropped below $2/m². Mass adoption in distributed PV projects is expected this year. Experts project this innovation could reduce solar power costs by $0.004/kWh, accelerating clean energy transition. Products-IOTA
