It’s abundantly clear that General Electric (GE) sees renewable energy and clean technology as a prime strategic business opportunity in the years ahead. From building the world’s largest wind turbines right on through to manufacturing solar-powered carports and electric vehicle charging stations, the multinational industrial engineering and financial services giant has its fingers in just about every renewable energy and clean tech pie you can think of.

Now, GE is expanding its thin-film solar panel manufacturing business, and in a big way. In April, GE announced its intention to build the US’ largest thin-film solar photovoltaic (PV) panel, this despite the oversupply and precipitous, 40% price drop that has occurred over the past two years.

DuPont's Thin Film Solar Bet for China and Beyond

California, USA — Amorphous silicon solar technology once seemed promising enough to gobble up a large market share. But it seems to have fallen out of favor in the past year, particularly since Applied Materials announced a year ago that it would no longer sell equipment to make amorphous silicon solar panels. Not only have some of its customers struggled to scale up manufacturing, the customers of its rivals also have had trouble doing the same because of financial or technical difficulties.

But amorphous silicon technology isn’t dead, as Tom Cheyney at PV-tech showed in this story. In fact, DuPont, better known for its materials that encapsulate and protect solar cells from moisture, ultraviolet radiation damage and other environmental enemies, has been churning out amorphous silicon solar panels at its factory in Shenzhen, China, through a subsidiary called DuPont Apollo.
