The Heat Affected Zone is limited and the material can be handled relatively soon after the annealing is complete. Researchers at ASP 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%.
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.
“There’s a lot of research going on now to increase solar panel efficiency,” said Maureen McHale, ASP 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.”
