lingotto

MULTICRISTALLINE

SOLAR INGOT G5

The ingot is the first manufacturing step of the photovoltaic module. Through a melting process and the subsequent solidification of the silicon it gets an ingot of 450 kg with dimensions 840 x 840 x 270 mm. The quality of used silicon and the doping process determine about 80% of the efficiency of the cells which will be obtained from a given ingot.

SOLAR BRICK

The bricks are obtained by squaring the ingot. The ingot is cut in 25 equal parts and these are then separated from their top, bottom and side appendices wherein, thanks to the process of directional solidification, have been settled all the impurities. Once squared every brick has a regular size of 156 x 156 x 210 mm and is ready to be sliced into wafers

SOLAR WAFER

Through a subsequent cutting process, the bricks are sliced into wafers of the size of 156 x 156 mm, with a thickness of 200 microns. The current standards of production allow for approximately 46 wafers per kg of brick. Out of an ingot of 450kg it will get about 15,000 wafers.

SOLAR CELLS

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.
