Diketopyrrolopyrrole (DPP) functionalized with 2-(3-cyano-4,5,5-trimethylfuran-2(5H)-ylidene) malononitrile (TCF) material coined as DPP-TCF was designed and synthesized. DPP-TCF exhibited strong absorption bands in solution as well as thin-film form. Herein, we report construction of dye sensitized solar cells (DSSCs) based on DPP-TCF anchored on CdS nanowires (NWs) coated on fluorine doped tin oxide (FTO) coated glass substrate with the device architecture FTO/CdS compact/CdS nanowire/DPP-TCF chromophore/electrolyte/ platinum coated FTO. As-fabricated DSSC device based on DPP-TCF and CdS nanowires exhibited power conversion efficiency (η) of 0.427%. Thus, the present work successfully displayed the utilization of DPP-TCF as an efficient light harvester in DSSC applications. This approach can also be employed to design and development of other DPP based organic molecular chromophores for DSSC applications.

2-(3-氰基-4,5,5-三甲基呋喃-2(5H)-亚基)丙二腈功能化二酮吡咯并吡咯:合成和太阳能电池应用

设计并合成了2-(3-氰基-4,5,5-三甲基呋喃-2(5H)-亚基)丙二腈( TCF )功能化的二酮吡咯并吡咯( DPP )材料,称为DPP-TCF 。DPP-TCF在溶液和薄膜形式中均表现出强吸收带。在此,我们报告了基于DPP-TCF锚定在涂有氟掺杂氧化锡 (FTO) 涂层玻璃基板上的 CdS 纳米线 (NW) 上的染料敏化太阳能电池 (DSSC) 的构建,器件架构为 FTO/CdS 紧凑型/CdS 纳米线/ DPP -TCF发色团/电解质/镀铂FTO。基于DPP-TCF和 CdS 纳米线的 DSSC 器件的功率转换效率 (η) 为 0.427%。因此,目前的工作成功地展示了DPP-TCF在 DSSC 应用中作为高效光收集器的用途。该方法还可用于设计和开发用于 DSSC 应用的其他基于 DPP 的有机分子发色团。
