In this study, we prepared thiophene-(N-aryl)pyrrole-thiophene (TPT)-based two new metal-free organic sensitizers (TPTDYE 2 and TPTDYE 3) with the aim of improving the dye-sensitized solar cell (DSSC) performance of recently reported TPT-based organic sensitizer (TPTDYE 1). The molecular structure of TPTDYE 1 was tuned by decreasing the distance between the donor and acceptor groups (TPTDYE 2) or by
在这项研究中,我们制备了以噻吩-(N-芳基)吡咯-噻吩(TPT)为基础的两种新型无金属有机敏化剂(TPTDYE 2和TPTDYE 3),目的是提高染料敏化太阳能电池(DSSC)的性能。最近报道的基于TPT的有机敏化剂(TPTDYE 1)。TPTDYE 1的分子结构可通过减小供体基团和受体基团之间的距离(TPTDYE 2)或通过在苯环上将氟原子引入电子接受氰基丙烯酸基团(TPTDYE 3)来进行调节。)。对新合成的敏化剂的光物理和电化学研究表明,与TPTDYE 1相比,它们的吸收和能级显着改变。对TPTDYE 2和TPTDYE 3增敏剂在有和没有共吸附剂的情况下的DSSC性能进行了研究,并与TPTDYE 1和标准N719进行了比较。在这两种DSSC之间,被TPTDYE 2敏化的DSSC大大提高了太阳能与电能的转化效率,无助吸附剂时为6.85%,有助吸附剂时为7.06%。TPTDYE 2敏化的
