Hybrid bulk heterojunction solar cells based on inorganic‐nanowire (NW)/conjugated‐polymer composites have been shown to achieve a power conversion efficiency (PCE) of 1–3 %, which is much lower than theoretically expected. This work addresses the short exciton diffusion lengths in common photoactive polymers with a new solar‐cell design that has a PCE of 4.68 % (see scheme; ITO=indium tin oxide, G‐PEDOT:PSS=glycerol‐doped poly(3,4‐ethylenedioxythiophene)‐poly(styrenesulfonate); E=electropolymerized; a=amorphous).
