A donor-acceptor conjugated copolymer enables the formation of nanowire systems that can be successfully introduced into bulk-heterojunction organic solar cells. simple binary solvent mixture makes polarity control possible allows kinetic over self-assembly crystalline polymer a structure during film-forming process. The enhanced photoconductivity nanowire-embedded photoactive layer efficiently facilitates photon harvesting in resultant maximum power conversion efficiency is 8.2% conventional single-cell structure, revealing 60% higher performance than devices without nanowires.
