染料敏化太阳能电池由于其易于加工以及其材料的丰富性和低成本而成为传统太阳能电池的有吸引力的替代品。然而，这些电池中的对电极采用铂，这显著影响它们的成本。在这里，我们报告了生物质衍生的氮掺杂碳气凝胶作为染料敏化太阳能电池的传统铂基对电极的有效替代品。以油胺为粘合剂，在DMF中制备了稳定的生物质衍生氮掺杂碳气凝胶悬浮液。对氮掺杂碳气凝胶电极进行了不同温度的退火处理，研究了退火处理对碳气凝胶电极光伏性能的影响。I-V测量证实，退火温度大大提高了这些设备的光伏参数，这些增强与有机粘合剂的去除。对电极的电化学阻抗谱证实，去除氮掺杂的碳气凝胶中的油胺降低了所得电极的串联电阻。从优化的氮掺杂的碳气凝胶的太阳能电池的功率转换效率表现出与使用铂基对电极制造的电池相当的效率。这项研究证明了生物质衍生的碳气凝胶作为DSSC中铂的廉价和可持续替代品的潜力。
Dye sensitized solar cells have emerged as an attractive alternative to conventional solar cells due to their easy processing and the abundance and low cost of their materials. However, the counter electrode in these cells employs platinum which significantly impacts their cost. Here, we report biomass-derived, nitrogen-doped carbon aerogel as an effective alternative to conventional platinum-based counter electrodes for dye sensitized solar cells. A stable suspension of biomass-derived, nitrogen-doped carbon aerogel was prepared in DMF by using oleylamine as a binder. The nitrogen-doped carbon aerogel electrode was annealed at different temperatures, and its impact on photovoltaic performance is investigated. I-V measurements confirm that the annealing temperature substantially enhances the photovoltaic parameters of these devices; these enhancements are linked to the removal of the organic binders. Electrochemical impedance spectra of the counter electrodes confirm that removal of oleylamine in nitrogen-doped carbon aerogels reduces the series resistance of the resulting electrodes. The power conversion efficiency of the solar cells from optimized nitrogen-doped carbon aerogel exhibited comparable efficiency to that of a cell fabricated using a platinum-based counter electrode. This study demonstrates the potential of biomass-derived carbon aerogels as a cheap and sustainable replacement of platinum in DSSCs.
