Through a series of chemical and thermal processes every single silicon wafer is converted into a photovoltaic cell. The cells are the soul of a module and ensure its ability to generate energy. The dimensions of a cell are the same as those of the wafer from which it originates, the typical blue color is due to antireflective process.

Since 2009, Lux produces multi crystalline ingots for photovoltaic applications in its plant in Alessandria. Through different cutting operations, the ingots become wafers which are later transformed into multi crystalline cells. The latest become photovoltaic modules, once assembled and welded together.
Alongside to its production, Lux can provide an ingot growing service, processing the silicon supplied by potential partners or grow ingots for R&D purpose for cutting tools and machines manufacturers.
