First Solar (Nasdaq: FSLR) designs and manufactures solar modules using a proprietary thin film semiconductor technology.
In 2013, General Electric announced that it was selling its solar panels business to First Solar. The deal included the sale of cadmium telluride thin film technology, which First Solar will use in its plants. GE had previously announced construction of a $300MM plant to make solar panels in Aurora, CO. That investment is now on hold.
