Moser Baer multicrystalline solar cells are manufactured from highly purified polysilicon in a state-of-the-art manufacturing plant that permits the use of thin silicon wafers. The manufacturing process uses sputtering for silicon nitride deposition and produces uniformly colored cells to ensure higher energy yields throughout the cell life.

Cell Features

	High energy yield with efficiency levels that remain stable in the long run
	Anti-reflection coating to improve light absorption and to increase cell performance
	Two busbars for maximum stringer compatibility

Manufacturing Excellence

	Automatic cell sorting into 32 separate bins based on IEC 60904-1 guidelines
	Cells calibrated to reference cells from Fraunhofer ISE cell lab, Germany, traceable to NIST standard
	ISO 9001 and ISO 14001 certified manufacturing plant

Highest Quality Standards

	Proprietary wafer inspection system to carry out 100% incoming wafer inspection to ensure highest wafer to cell yields
	Bar-coded packaging to facilitate complete “wafer to cell” electronic data trail
