A team of researchers at MIT has devised a technique to create solar cells that are just two molecules thick. Though the resultant solar cell can offer conversion efficiency of just 1-2 per cent, on placing multiple cells on top of the other, it is possible to increase the overall capacity, as compared to the conventional cells.  The latest trend in solar cell research has been on enhancing the conversion efficiency of solar cells. As a result, most solar cells can now generate 15 -20 per cent of the solar energy they get into electricity and the most efficient modules operate at 30 per cent efficiency level. Researchers at MIT are now planning to turn their research into a new direction. They are now working on making the solar cells much thinner and use fewer materials. In their research paper titled “Extraordinary Sunlight Absorption and 1 nm-Thick Photovoltaics using Two-Dimensional Monolayer Materials” they have explained how they have developed a technique to create solar ce
