The highest efficiency OPV at present use low-bandgap donor polymers, many of which suffer from problems with stability and synthetic scalability. They also rely on fullerene-based acceptors, which themselves have issues with cost, stability and limited spectral absorption. Here we present a new non-fullerene acceptor that has been specifically designed to give improved performance alongside the wide bandgap donor poly(3-hexylthiophene), a polymer with significantly better prospects for commercial OPV due to its relative scalability and stability. Thanks to the well-matched optoelectronic and morphological properties of these materials, Nature communicationsHigh-efficiency and air-stable P3HT-based polymer solar cells with a new non-fullerene acceptor.PMC4906164EP/J021199/1EP/M023532/11648728Dimitrov SDLaquai FHolliday STan CHBrabec CJAlamoudi MGasparini NDurrant JRWadsworth ANielsen CBMcCulloch IBaran DSalleo AShang ZYousaf SAAshraf RSfalseHigh-efficiency and air-stable P3HT-based polymer solar cells with a new non-fullerene acceptor.Solution-processed organic photovoltaics (OPV) offer the attractive prospect of low-cost, light-weight and environmentally benign solar energy production.
