Oxford researchers try to reduce solar power costs

Help

University of Oxford scientists have discovered a way to make solar cells from a metal oxide found in toothpaste.

A team led by Dr Henry Snaith at the physics department combined the oxide with a thin dye printed on to glass to turn the sun's energy into electricity.

The glass can be produced in a range of different transparent colours for use in windows and cladding buildings.
