Raising the efficiency of solar cells with Luminescent LED

Solar cells have a limited capacity in getting  sunlight and convert it into electric energy.

This limit can now be extended, due to the research team from the University of California, Berkley.

Acording to the researchers solar cells should be made to work like LEDs that will perform the dual function of absorbing as well as emitting light. This way its efficiency will be better and it will produce higher voltage.

The study shows that there was indeed a mathematical connection between the efficiency of solar cells,their absorption and light emitting capacity.Of course you should
know exactly how this system works and what makes it more efficient.

The process begins when photons from the sun hit the electrons and the energy so produced knocks free the electrons to flow freely.Unconnected photons are produced  through a process called luminescence. These unconnected photons have to be released.

Emitting photons will give higher voltage and also greater efficiency. The researchers hope to achieve 30 percent efficiency for solar cells.
