Two for One in Solar Power

Solar cells offer the opportunity to harvest abundant, renewable energy. Although the highest energy light occurs in the ultraviolet and visible spectrum, most solar energy is in the infrared. There is a trade-off in harvesting this light, so that solar cells are efficient in the infrared but waste much of the energy available from the […]

New Solar Cell Converts Infrared Light to Electricity

  Guest Post   Traditional solar cells, most of which are based on crystalline silicon, are only able to make useful electricity of solar radiation in the visible range. A research team at MIT led by professor Michael Strano has just announced that they have successfully created a solar cell based on carbon that converts […]
