University Of Michigan researchers are trying to eliminate traditional semiconductor based solar cells to generate solar power. A recent discovery revealed unknown properties of light which may lead to creating optical battery which will eliminate the need of solar cells - an integral part of the traditional solar power production mechanisms.

It's a well known fact that light has electro-magnetic components. The effect of magnetic field of light was so small that researchers ignored it until now. However, Professor Stephen Rand and his team at Electrical Engineering & Computer Science department of University Of Michigan discovered that when light of specific intensity travels through a material that does not conduct electricity, light field can generate magnetic effect about 100 million times than expected.

The discovery is still in nascent sstage and it may take a while for the technology to be available for mass consumption. It's however clear that mankind is taking rapid steps towards clean & green energy.
