Solar paint?

One day, a thin film of ‘solar panel’ could be painted over windows and walls to turn every home into a giant hi-tech ‘sun trap’.

The hi-tech solution could make solar energy a practical solution t the energy crisis.

The technology has long been championed as a solution to the growing energy crisis, but as it exists now, it is far too expensive.

A typical home needs around 285 square feet of solar panels to meet its electricity needs, costing around £10,000, although that does not include the expensive installation.

Scientists at USC have developed a potential pathway to cheap, stable solar cells made from nanocrystals so small they can exist as a liquid ink and be painted or printed onto clear surfaces.
