New type of photovoltaic device harnesses heat radiation that most solar cells ignore. About 40 percent of the solar energy reaching Earth’s surface lies in the near-infrared region of the spectrum — energy that conventional silicon-based solar cells are unable to harness. But a new kind of all-carbon solar cell developed by MIT researchers could tap into that unused energy, opening up the possibility of combination solar cells — incorporating both traditional silicon-based cells and the new all-carbon cells — that could make use of almost the entire range of sunlight’s energy. The new cell is made of two exotic forms of carbon: carbon nanotubes and C60, otherwise known as buckyballs. “This is the first all-carbon photovoltaic cell,” Strano says — a feat made possible by new developments in the large-scale production of purified carbon nanotubes. “It has only been within the last few years or so that it has been possible to hand someone a vial of just one type of carbon nanotube,” he says. In order for the new solar cells to work, the nanotubes have to be very pure, and of a uniform type: single-walled, and all of just one of nanotubes’ two possible symmetrical configurations.

The new report shows that the global cumulative installed solar PV capacity increase of 100% demonstrated during 2009-2011 is likely to grow even further as mass power consumers China and the US reach grid parity within the next few years.
The agreement enables First Solar to continue construction activities of the 230-megawatt power plant that, when completed in 2013, will generate enough electricity to power 75,000 homes.
