Yingli Green Energy Holding Co. Ltd. and Heraeus have signed a $70 million cooperation and supply agreement.
Heraeus' PV unit, which develops front- and back-side silver paste for crystalline solar cells, will work together with Yingli Green Energy to achieve photovoltaic technology advancements – specifically to reduce the cost-per-watt of solar cells to a new industry benchmark.
Under this new one-year agreement, Heraeus will now dedicate research and development resources in its three technology centers to develop new silver metallization pastes for Yingli Green Energy's N-type silicon solar cells known as PANDA.
