It is difficult to get a photovoltaic cell that can absorb a wide wavelength of light. These Holographic Solar photovoltaics bring in a solution to this. Prism Solar Technologies has developed the holographic concentrators that boost the efficiency per square inch of photo-cell by 25%. And this increase is no joke from the prevailing global power-crisis point of view.
It is economic not only for its efficiency, but also because the concentrators are cheaper compared to the silicon solar cells. They are also less environmentally costly to create.
