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。本研究报道了CO2和Na反应制备三维石墨烯作为DSSCs的对电极（CE）。石墨烯CE的DSSCs比Pt CE具有更高的功率转换效率（PCE）。此外，用食用染料红素B代替昂贵的钌基染料（N7I9或N3）。这为利用二氧化碳生产石墨烯和制造低成本DSSCs提供了一种新方法。(C) 2020 Elsevier B.V.版权所有
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 (N7I9 or N3). This provided a novel approach for CO2 utilization on producing graphene and for fabricating low-cost DSSCs. (C) 2020 Elsevier B.V. All rights reserved.
