Abstract Dye-sensitized solar cells (DSSCs) provide an efficient method to convert the solar energy into electricity. In this study, the reaction of CO2 and Na to produce 3D graphene as counter electrode (CE) for DSSCs was reported. DSSCs with graphene CE exhibited higher power conversion efficiency (PCE) compared with Pt CE. Furthermore, food dye Erythrosin B was employed to replace the expensive ruthenium based dyes (N719 or N3). This provided a novel approach for CO2 utilization on producing graphene and for fabricating low-cost DSSCs.

将 CO2 转化为 3D 石墨烯作为食品染料敏化太阳能电池的对电极

摘要 染料敏化太阳能电池(DSSCs)提供了一种将太阳能转化为电能的有效方法。在这项研究中,报告了 CO2 和 Na 反应产生 3D 石墨烯作为 DSSC 的对电极 (CE)。与 Pt CE 相比,具有石墨烯 CE 的 DSSC 表现出更高的功率转换效率 (PCE)。此外,食用染料赤藓红 B 被用来代替昂贵的钌基染料(N719 或 N3)。这为利用二氧化碳生产石墨烯和制造低成本 DSSC 提供了一种新方法。
