Cheap Silicon Means Cheaper Solar Cells

Article Abstract: Designer Edge

The Engineer posted on November 07, 2014
“We’re using less expensive raw materials, and smaller amounts of them,  we have fewer production steps and our total energy consumption is potentially lower,” explain PhD candidate Fredrik Martinsen and Professor Ursula Gibson, from NTNU’s Department of Physics.
They recently published their technique in Scientific Reports. Their processing technique allows them to make solar cells from silicon that is 1000 times less pure, and thus less expensive, than the current industry standard.
