John A. Rogers who is an eminent professor of materials science and engineering at the University of Illinois has devised a way to trap the solar energy in better ways. Until now, one could only harness solar energy through solid and fixed panels that absorbed solar energy, which would later be converted to other forms of energy.

He has discovered a technology through which one can print ultra thin and semi transparent cells which are flexible on cloth, canopies, glass etc. Since this can even be printed on fabric, harnessing solar energy in a permanent way become easier.

In fact, using this technology to build solar equipped products is one of the best way to reduce emissions and also save energy. Unlike traditional silicon solar cells, these flexible cells are not rigid, heavy and opaque. Thus, there seems to be a glimmer of hope again for those who have sworn by the success of solar energy.
