Researchers have developed a silicon dioxide (SiO2) coating for photovoltaic (PV) modules that enhances light transmission and thermal performance, according to a study published in a peer-reviewed journal. The coating is designed to reduce reflection and improve heat dissipation, which can increase the overall efficiency of solar panels.
The study, conducted by a team at a European university, found that the SiO2 coating increased light transmission by up to 3% compared to uncoated glass. This improvement allows more sunlight to reach the solar cells, boosting electricity generation. Additionally, the coating helped lower the operating temperature of the modules by several degrees Celsius, which is beneficial because high temperatures reduce PV efficiency.
The coating is applied as a thin layer on the front glass of the module. It is transparent, durable, and resistant to environmental factors such as moisture and UV radiation. The researchers tested the coating under simulated sunlight and outdoor conditions, confirming its stability over a period of six months.
This innovation could be particularly useful for large-scale solar installations, where even small efficiency gains translate into significant energy output. The team is now working on scaling up the production process and plans to conduct longer-term field tests to assess the coating's durability over several years.
