with respect to that in solution; iii) an improvement in the electron distribution of the donor unit to distinctly increase the photo‐stability of synthetic intermediates and final sensitizers. The stability and spectral response of indoline dye‐based DSSCs are improved by the strong electron‐withdrawing benzothiadizole unit in the conjugation bridge. The incident‐photon‐conversion efficiency of WS‐2
提出了一种新颖的概念“D-A-π-A”有机敏化剂,代替了传统的D-π-A敏化剂。值得注意的是,结合的低带隙,强电子吸收性苯并
噻二唑在光收集和效率方面显示出一些有利的特性:i)优化的能级,导致进入NIR区域的波长的响应范围大;ii)薄TiO 2上的吸收峰有很小的蓝移关于解决方案的影片;iii)改善供体单元的电子分布,以明显提高合成中间体和最终敏化剂的光稳定性。共轭桥中强的吸电子苯并
噻二唑单元可改善基于
吲哚染料的DSSC的稳定性和光谱响应。WS-2的入射光子转换效率达到近850 nm,在液体电解质中的功率转换效率高达8.7%,在
离子液体电解质中的功率转换效率高达6.6%。
