Solar power offers one of the most exciting options for renewable sources of energy. As the industry grows, the use of fiber lasers remains vital in driving both photovoltaic cell efficiency and manufacturing processing times and yields. Today, two photovoltaic technologies compete for market dominance: crystalline silicon (c-Si) and thin film - multiple layers of semiconductor materials deposited onto a base substrate. IPG’s low cost fiber lasers such as YLPN near-infrared nanosecond fiber lasers, green GLPN and ultraviolet ULPN pulsed lasers positively impact photovoltaic manufacturing costs since laser-based processes are significantly more efficient, precise and are faster than conventional processes due to high wall-plug efficiency, excellent beam quality for tight process control and fast, high repetition rate pulses. Additionally, thin film photovoltaics draw from similar knowledge for applications such as thin film patterning, scribing and edge deletion to similarly improve manufacturing throughput and costs.

Systems capabilities include crystalline silicon (c-Si) wafer downsizinghigh speed drilling, and selective annealing, as well as integrated systems for micro material removal such as thin film patterning, scribing and edge deletion.

Photovoltaics manufacturers benefit from IPG's extensive application knowledge and expertise in building integrated systems that improve manufacturing quality, throughput and costs.
