Solar dyes give a guiding light

(13 Jul 2008)
“A new way of capturing the energy from the Sun could increase the power generated by solar panels tenfold, a team of American scientists has shown.

The new technique involves coating glass with a specific mixture of transparent dyes which redirect light to photovoltaic cells in the frame.

The technology, outlined in the journal Science, could be used to convert glass buildings into vast energy plants. ”
