39 Ways to Save the Planet - More Power from the Sun

Electricity from the sun is cheap and clean but the solar cells we see on our rooftops could be much more efficient. Henry Snaith of Oxford PV has developed a new material which helps solar roof panels extract more energy from the solar spectrum. Tom Heap visits Henry's lab and joins Dr Tamsin Edwards to consider the carbon-cutting potential of a new generation of solar energy.
