Lasers have been widely used for the production of traditional solar cells, such as PERC type PV cells. The laser is used to open the oxidation layers on the backside in what is known as the Laser Contact Opening (LCO) process, often employing top hat beam shaping to obtain a uniform ablation profile with fixed … Continue reading
