Scientists are getting excited about perovskites:
They are more efficient at generating electricity from sunlight than current photo-electric cells and they are cheaper to produce.
The day is nearer when we will be able to generate our own electricity through the sunlight falling on our windows, rather than relying on the energy companies burning fossil fuel to generate it and deliver it to us over miles of cable.
All we need now is a bright spark to develop fridges and cookers which don’t need 240 volts and 13amps, but can operate on much less. Many of the devices in my flat have transformers to reduce 240 volts to 12 or 19. If we are doing the generating, we can do without these transformers.
