A team of researchers at the University of Kansas have studied a counterintuitive effect in organic semiconductors that may lead to competitive solar cell efficiencies. They found that non-fullerene acceptors (NFAs) may help bridge the efficiency gap, with efficiencies closer to 20%. The significant boost in performance occurred from a counterintuitive effect where some excited electrons gained energy from the environment. The mechanism can be used to make more efficient solar cells and may have applications in solar-fuel production.
