Silicon is used both in semiconductors and solar cells. Because of the boom in the solar energy industry, there has become a shortage of processed silicon, and this bottleneck is holding back the solar cell manufacturers from using their full capacity.
Now a startup company has found a new, more efficient way to process the material, so the production cost for silicon used in silicon solar cells -- which needs not to be as pure as the silicon used for hard drives -- could be reduced. They hope this could help to make the price of solar energy comparable to the grid price of electricity.
They have received $ 20 million in a second round funding and will start manufacturing by the end of the year.
