摘要
在染料敏化太阳能电池(DSCs)中使用铂电极作为对电极(CEs)面临着巨大的经济和环境挑战。针对这些困难,本研究利用农业废弃物稻壳制造出适用于 DSC CE 的活性炭。通过简单的喷雾热解技术,从稻壳中获得了活性炭。采用稻壳活性炭作为 CE 的 DSC 转换效率为 6.06%,略低于铂电极电池的 8.21% 转换效率。然而,与贵金属替代品相比,使用低成本的活性炭可大幅降低成本,从而掩盖了这一性能差距。这一结果为研究在 DSC 中使用从农业中提取的碳材料作为铂 CE 的可行且经济的选择提供了前景广阔的途径,从而为光伏系统的可持续发展做出了贡献。尽管使用稻壳活性炭作为 CE 的 DSC 性能略低于使用铂的同类产品,但使用低成本的贵金属活性炭可显著降低成本。
Active carbon derived from rice husk as sustainable substitutes for costly platinum electrodes in dye-sensitized solar cells
Significant financial and environmental challenges are associated with using platinum electrodes as counter electrodes (CEs) in dye-sensitized solar cells (DSCs). This work uses rice husk, an agricultural waste, to create active carbon that is appropriate for DSC CEs in response to these difficulties. A simple spray pyrolysis technique created activated carbon obtained from rice husks. The DSC employing activated rice husk carbon as the CE demonstrated a conversion efficiency of 6.06%, slightly lower than the 8.21% efficiency achieved with a platinum electrode-based cell. However, this performance gap is overshadowed by the substantial cost reduction enabled by the utilization of low-cost activated carbon compared to noble metal alternatives. This result introduces promising avenues for investigating the use of agriculturally derived carbon materials as workable and affordable options for platinum CEs in DSCs, thereby contributing to the sustainable advancement of photovoltaic systems. Even though the performance of DSC that uses activated carbon derived from rice husk in CE is slightly lower than its counterparts based on platinum, the cost reduction due to the use of low-cost activated carbon with noble metal is significant.
期刊介绍:
In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research.
Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science.
With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
