Molybdenum Sputtering Targets, Silicon Nitride Powders
Improved Cost/Watt Ratio for Photovoltaics
Molybdenum sputtering targets for back contacts in CIGS and CdTe solar modules directly address the pressing need to improve the cost/watt ratio in the manufacturing of thin film PV modules; silicon nitride crucible coatings facilitate silicon ingot production.
Monolithic rotary targets from H.C. Starck offer good density and uniformity and prolonged lifetimes for use in photovoltaics production. High-grade Si3N4 powders meeting the purity requirements set by ingot/wafer producers are also available from the same company. Silica crucibles used for melting and crystallizing silicon are coated on their inside surface with a Si3N4-based coating which facilitates easy release of the ingot after finishing the production cycle, prevents impurities from entering the silicon, and minimizes stress created during solidification.
