Dramatically reducing the cost of solar panels
A watt of solar energy was worth $77 back in 1977. Now it’s worth about 80 cents.
But in order for solar panels to really replace conventional sources of energy, we need them to get even cheaper.
Some companies are harvesting their environment to disrupt the energy market while Henry Snaith of Oxford is trying to dramatically reduce the cost of solar energy:
Dr Snaith plans to replace silicon, the material used to make most solar cells, with a substance called a perovskite. This, he believes, could cut the cost of a watt of solar generating capacity by three-quarters.
