photovoltaic properties of the dyes were studied. In general, DSSCs fabricated with the dyescontaining cyanovinyl thiophene unit as a π-spacer shows more than two times higher efficiency than the DSSCs fabricated without cyanovinyl thiophene unit. The maximum power conversion efficiency of 3.01% was achieved for the cyanovinyl thiophene unit in the π-spacer and acrylic acid acceptor dye based DSSC.
series of metal-free organicdyes containing diphenylamine or diethylamine as a donor which is linked to the acrylic acid or rhodanine-3-acetic acid as a acceptor and phenyl π-spacer were synthesized through one-pot Knoevenagel condensation reaction which are used as photosensitizers for the application of dye-sensitizedsolarcell (DSSC). Photophysical, electrochemical and DSSC performances were studied
通过单锅Knoevenagel缩合反应合成了一系列不含金属的有机染料,含有二苯胺或二乙胺作为供体,与丙烯酸或罗丹-3-乙酸作为受体和苯基π间隔物相连。用于染料敏化太阳能电池(DSSC)的光敏剂。研究了合成染料的光物理,电化学和DSSC性能,其中二苯胺供体和丙烯酸受体基染料(Ar-ma)在AM1.5光照(85 mW cm -2)下表现出高的电子寿命和最大的功率转换效率。电化学阻抗谱结果及其理论计算与DSSC输出性能具有很好的一致性。

Disclosed is an organic photoconductive material for the electrophotography, which comprises a linear high-molecular-weight polymer having a rhodanine derivative of the following formula incorporated as a substituent: ##STR1## In this derivative group, a benzylidene group or the like is bonded to the 5-position of the rhodanine ring. A photosensitive material comprising a polymer having this rhodanine derivative group shows a photoconductivity to visible rays even without addition of a charge-generating pigment.
