Scientists use windows to trap solar energy
A team from scientists MIT have created a new technique that involves coating windows with special chemical dyes, The team's discovery could transform buildings into energy plants. The scientists say their dyes can produce ten times more power than the traditional solar panels used around the world today.
As this radiant energy collides with opaque objects on the other side of the glass, it’s wavelength increases to 11 microns, The amount of light penetrating a glass is dependent on the angle of incidence; The team believes that it could be implemented within three years - even added onto existing solar-panel systems to increase their efficiency by 50 percent for minimal additional cost substantially reducing the cost of solar electricity.

The MIT engineers revived the idea end used coloured dyes to stop the light from escaping MIT's development also does away with the need for hundreds of bulky solar cells. MIT's Professor Baldo explained.
A glass would let through about 10 per cent of the Sun to light up the room, and the edges to solar cells to generate electricity…" The new discovery could help fight climate change.
