Amtech Discloses Previously Announced Large Solar Order in December is from Yingli - 300MW PANDA Mono-Crystalline Expansion Project

J.S. Whang, President and Chief Executive Officer of Amtech, commented, "This large order from Yingli is a result of the successful high efficiency cell collaboration project we announced in a press release last June among Yingli, the Energy Research Centre of the Netherlands (ECN) and Tempress Systems, Amtech's solar subsidiary, to develop next generation high efficiency solar cells. We are very pleased to be an essential part of the PANDA project and to receive such a significant follow-on order from one of the world's leading vertically integrated photovoltaic product manufacturers in the world. We believe this will help our client further increase their cell conversion efficiency to their target level."
