Marking five years of successful collaboration, DuPont Microcircuit Materials (MCM), part of DuPont Electronic Technologies, today announced that it is the proud recipient of a Q-Cells Supplier Award for its provision of metallization materials used in the construction of silicon photovoltaic cells.
Citing DuPont’s excellent supply performance over this period, Q-Cells presented the award to DuPont at last month’s European Photovoltaic Solar Energy Conference and Exhibition in Dresden, Germany. Q-Cells AG, based in Thalheim, Germany, is Europe’s biggest manufacturer of high-performance solar cells made of mono- and multicrystalline silicon.
The cooperation between the two companies started in the first six months of 2001, when Q-Cells began producing photovoltaic cells. DuPont MCM, under the brand name DuPont Solamet, provided Q-Cells with silver pastes for the front-side of the cells to fire through the ARC (anti-reflective coating) and penetrate into the silicon to achieve a good ohmic contact without shunting.
Other thick film metallization pastes within the DuPont Solamet range include aluminium pastes to secure a good ohmic contact with the backside (p-side) and the silver, or silver/aluminium pastes, which are soldered to the interconnect ribbon. These, in turn, electrically connect the cells together, either in a series or in parallel.
Commenting on the company’s decision to make DuPont a recipient of its service award, Matthias Raetz, head of Supply Management at Q-Cells said, “We are aware that we owe the excellent performance of our company also to the excellent performance of our suppliers. Our stable and lasting relationship with DuPont, as a supplier of high-performance materials, also supported our success.”
