Even Cheaper Solar Cells

We recently reached the point that solar power is cheaper than nuclear power and now some researchers at the University of Toronto have found a way to make solar cells even cheaper by using nickel instead of gold.

One of the major drawbacks of most renewable energy sources is high cost. In order to see a huge rise in the use of renewable energy sources, prices must come down. In the world of solar there have recently been some major breakthroughs in cost advantages and efficiency increases. Scientists at the University of Toronto in Canada have come up with a way to reduce colloidal quantum dot solar cell prices by up to 80%, by swapping out costly conductive gold for cheap nickel.
