Cheaper silicon means cheaper solar cells

A new method of producing solar cells could reduce the amount of silicon per unit area by 90 per cent compared to the current standard. With the high prices of pure silicon, this will help cut the cost of solar power.

“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.
