“Nano-Filament” Solar Cell Breaks Efficiency Record
Science Daily reports researchers at the Wake Forest University’s Center for Nanotechnology and Molecular Materials have announced that they have increased the efficiency of plastic solar cells to more than 6 percent. Wake Forest researchers credit the record efficiency for organic or flexible plastic solar cells to “non-filaments” within light absorbing plastic, similar to veins in tree leaves. In order to be considered for commercial use, solar cells must be able to convert 8 percent of the energy in sunlight to electricity. Having doubled the 3 percent mark in only two years, Wake forest researchers hope to reach 10 percent in the next year.
