New Technology Could Double Solar Cell Efficiency

New Technology Could Double Solar Cell Efficiency

But what if the cost were to drop significantly? Then, there would surely be no excuse not to go solar. The cost of the panels themselves has more or less stabilized, but what if the amount of power that comes out of each panel were to go up by a factor of two? Current technology has a cell efficiency of 31 percent. This is largely limited by the fact that much of the sun’s energy is contained in a part of the spectrum that is “too hot” for existing panels to capture and convert to electricity. If this part of the spectrum could be utilized, solar PV panels could come much closer to achieving their theoretical maximum efficiency of 66 percent.
