Traditionally, to anneal a coating on glass, the coating was applied to the glass, baked at 600 degrees Celsius, and then cooled for three to four hours. Using this new oven-less annealing process, the coating is applied to the glass and then a laser beam is swept over the surface to anneal. The Heat Affected Zone (HAZ) is limited and the material can be handled relatively soon after the annealing is complete. Researchers at Advanced Solar Photonics have discovered that with this newly developed oven-less laser annealing process the light transmission efficiency and conductivity of TCO layers are increased by up to 35%.
“There’s a lot of research going on now to increase solar panel efficiency,” said Maureen McHale, Advanced Solar Photonics Corporate Marketing and Public Relations Manager. “This new process is a huge breakthrough for Advanced Solar Photonics and the solar industry. Not only does using this new process increase efficiency, the e2process also lowers the electrical surface resistance, prevents de-lamination and performs recrystalization of amorphous silicon.”Glass that has been coated and annealed is used for such things as: architectural glass, as seen in large buildings and skyscrapers, windshields and solar panels.
Advanced Solar Photonics, located in Lake Mary, Florida employs an international team of technology driven professionals. Reaching out to the photovoltaic industry, ASP strives to lower manufacturing costs utilizing proven patented technology geared to improve and lower the cost per kilowatt. This technology is applicable to both the silicon and thin film processes.
