solar thermophotovoltaics surpass theoretical efficiency limit

Just a few years ago, solar thermophotovoltaics (STPV) was more of a theory than an actuality. The idea behind STPV is that the efficiency of solar modules will improve significantly if certain materials are used to trap the sun’s heat before it reaches the module. Photovoltaics, however, have always had certain limitations, as they can convert only a portion of sunlight into electricity. Since 1961, this limit—known as the Shockley-Quiesser limit, was thought to cap a solar cell’s efficiency around 32 percent. Read the rest of this entry »
