Demystifying Beam Splitting Technologies in Perovskite Photovoltaic Laser ProcessingThe transition to gigawatt-scale perovskite solar production hinges on precision laser processing, where beam splitting technology plays a pivotal role. By dividing a single laser source into multiple beams, this technique enables simultaneous scribing of P1-P3 patterns and edge isolation (P4), directly impacting throughput, dead zone control, and production costs. Current industrial approaches primarily include mechanical beam splitting and diffractive optical elements (DOEs), each with distinct advantages for perovskite’s thermal sensitivity and scalability requirements.
