Solar energy undoubtedly is one of the cleaner and greener power sources. But currently, the solar cells which harness the sun’s radiation and convert them into electricity aren’t cheap enough to be utilized at mass scale. Thus, the true potential of this renewable energy still remains to be channeled for the larger benefits of society.

But now, scientists at Massachusetts Institute of Technology have designed a new devise which they say is an efficient and practical solar power device. The latter acts as a solar concentrator and is considered to be a key in making solar energy more affordable in the near future. Scientists at MIT used several glass sheets and coated them with organic dyes to concentrate the sunlight hitting on the solar panes. The organic dyes upon absorption of sunlight emit it onto the glass sheet which in turn carries the light to the edges of the pane following the example of transport of light through fiber-optics. In this solar concentrator, small solar cells are located at the edges of the glass sheets.These cells convert sun’s photons into electricity.

Researches hope that this technology can bring down the cost of running a solar power unit down and much closer to that used by conventional methods of power generation (fossil fuel burning). The current type of solar concentrators available in the market use either lenses or mirrors to concentrate sunlight. However, in this new solar power device, glass sheets used are light weight and flat shaped. These can be used on roofs or as windows that could generate power for the entire house/ building. This new device is under testing and the final product ready for the market will become available in a couple of years. So far the news itself promises a sustainable tomorrow. I’m waiting when it actually becomes a reality!
