The joint project under the agreement will seek to develop and implement high efficiency N-type silicon solar cells, named PANDA, at Yingli Green Energy's pilot production line in Baoding, China. The high efficiency cells will utilise the cell design of ECN, the solar diffusion technology and dry PSG removal expertise of Tempress Systems, Inc., Amtech's solar subsidiary, and Yingli Green Energy's leading cell process technology.

The construction of the pilot production line does not require significant capital expense, according to the announcement, as it only requires moderate changes to the current production lines.
