A new invention that would allow domestic window to function as solar panels was recently invented by scientist at MIT in Boston. The real invention is a special coat that aplied to the windows conducts some of the light to the edges where the solar cells are. This has several advantages it allows for smaller solar cells lowering the cost of the installations, concentrates the light raising the eficiency as the solar cells are more eficient at higher light intensities. Another major saving is the unobtrusive installation that requires just a coat of the revolutionary material thus eliminating the need of expensive roof mounted panels or concentrators that need further cooling.
