performance of DSSC is described here. Dye‐sensitized solar cells (DSSCs) using dyes as the sensitizers exhibit good efficiencies, ranging from 3.06 to 6.35 %, which reached 42–87 % with respect to that of N719‐based device (7.33 %) fabricated and measured under similar conditions. Time‐dependent density functional theory (TDDFT) calculations have been performed on the dyes, and the results show that both
基于1-烷基-1 A系列施主-π-受主型有机染料的ħ咪唑间隔物1,2,3,4,5已经开发和表征。两个电子给体位于咪唑的4和5位,而电子接受的氰基丙烯酸在2位被含间隔基的杂芳环(如噻吩和噻唑)并入。此处详细描述了DSSC的结构,光谱和电化学性质与性能之间的关系。使用染料作为敏化剂的染料敏化太阳能电池(DSSC)表现出良好的效率,范围为3.06%至6.35%,相对于在相似条件下制造和测量的基于N719的器件(7.33%)而言,达到42-87%。对染料进行了随时间变化的密度泛函理论(TDDFT)计算,结果表明,两个电子供体在光激发时都可以促进电子注入,
