In a ground-breaking development scientists at Cambridge University are working on a prototype organic solar cell that could dramatically reduce the cost of green energy.
The new system uses two different types of carbon molecules, instead of silicon, which when mixed together separate into layers and start converting sunlight into power.
The device is still in early stages of development and so far has managed to convert just 34% of blue-green light to electricity.
To be of any real use it must be able to use light from the whole of the spectrum.
