First solar polycrystalline CdTe thin film PV

First Solar has been manufacturing and selling thin film PV modules commercially since 2002. The First Solar FS Series module product is a single-junction polycrystalline thin film structure that employs CdTe as the absorption layer and CdS as the window layer. First Solar's production process uses thin film semiconductor technology that integrates the entire solar module manufacturing process into a single production line. Since commencing commercial production in 2002, we have produced and sold 36.5MW of thin film CdTe solar modules. This presentation provides an overview of First Solar polycrystalline thin film technology, manufacturing, applications and field performance and potential for improvement.
