Abstract

In this article, we have synthesized N and S co-doped graphene quantum dots (SNGQDs) using low cost hydrothermal process. The particle size of SNGQDs is distributed within the range of 2-25 nm. Quantum dot sensitized solar cells (QDSSCs) were fabricated by attaching SNGQDs with ZnO nanorods grown on fluorine doped tin oxide (FTO) coated glass substrates. The SNGQDs sensitized ZnO NR photoanodes demonstrated power conversion efficiency ∼0.27%, which was 7 times higher than pristine ZnO nanorod based device.In this article, we have synthesized N and S co-doped graphene quantum dots (SNGQDs) using low cost hydrothermal process. The particle size of SNGQDs is distributed within the range of 2-25 nm. Quantum dot sensitized solar cells (QDSSCs) were fabricated by attaching SNGQDs with ZnO nanorods grown on fluorine doped tin oxide (FTO) coated glass substrates. The SNGQDs sensitized ZnO NR photoanodes demonstrated power conversion efficiency ∼0.27%, which was 7 times higher than pristine ZnO nanorod based device.

S, N共掺杂石墨烯量子点修饰ZnO纳米棒用于“绿色”量子点敏化太阳能电池

本文采用低成本水热法制备了氮、硫共掺杂石墨烯量子点(SNGQDs)。SNGQDs的粒径分布在2 ~ 25 nm范围内。将生长在氟掺杂氧化锡(FTO)镀膜玻璃衬底上的ZnO纳米棒与量子点敏化太阳能电池(QDSSCs)结合，制备了量子点敏化太阳能电池(QDSSCs)。SNGQDs敏化ZnO NR光阳极的功率转换效率为0.27%，是原始ZnO纳米棒器件的7倍。本文采用低成本水热法制备了氮、硫共掺杂石墨烯量子点(SNGQDs)。SNGQDs的粒径分布在2 ~ 25 nm范围内。将生长在氟掺杂氧化锡(FTO)镀膜玻璃衬底上的ZnO纳米棒与量子点敏化太阳能电池(QDSSCs)结合，制备了量子点敏化太阳能电池(QDSSCs)。SNGQDs敏化ZnO NR光阳极的功率转换效率为0.27%，是原始ZnO纳米棒器件的7倍。
