Solar market offers new opportunities for lasers

摘要

The most important objective for today's photovoltaic (PV) market is to reduce the ratio of manufacturing cost to power output, and more specifically for solar modules, the manufacturing cost per kilowatt hour (kWh). With this in mind, technical solutions are required to reach grid parity and make PV a competitive energy source. Lasers already have several applications in the PV manufacturing process such as edge isolation or cell structuring. This article will describe the PV industry from the production side and then focus on opportunities for laser manufacturers.
