原始语种摘要: Abstract(#br)Compared with the development of novel organic dyes, co-sensitization is a much more convenient way to achieve highly efficient dye-sensitized solar cells (DSSCs). Here, two simple donor-(π conjugated spacer)-acceptor dyes, in which hexyloxy-substituted phenyl as an electron donor, cyanoacrylic acid as the electron acceptor and different spacers thiophene ( LD03 ) or furan ( LD04 ) as the π-linkers, were designed and synthesized as co-sensitizers for N719 -based DSSCs. The photophysical, electrochemical, photovoltaic performances and electrochemical impedance spectroscopy of these DSSCs were investigated in detail. When compared to the DSSCs fabricated from individual N719 , the co-sensitized DSSCs ( N719 + LD03 and N719 ...
