求翻译：GCL EVP Jeff Shan used to lead the sales organization for Applied Materials based in Taiwan and China. He sold a lot of solar equipments to Suntech and LDK etc. China based companies before CEO of Applied Materials announced to stop new investment for aSi thin-film technology in July 2010. I am not sure which solar technology Solarpark will consider to invest in YanCheng but will suggest you offline consult some domain expertises if you're serious to support Solarpark and their thin-film solar technology because so far the only thin-film solar company making positive profit was First Solar (USA) who used CdTd technology instead of aSi and CIGS. Please understand Cd was restricted to use as one of RoHS materials.是什么意思？
