A one-year, US$70 million R&D and supply project is underway between materials supplier, Heraeus and Yingli Green. Resources are being allocated from Heraeus’ three global technology centres to develop next-generation silver metallization pastes for Yingli’s N-type ‘PANDA’ silicon solar cells.
The new collaboration comes on the back of other deals done with DuPont this year to both improve cell efficiencies and reduce the cost-per-watt. Silver is the second largest cost contributor in cell production, after polysilicon.
Development work will take place at Heraeus’ US, German and Singapore-based technology centres.
