摘要
为了解决染料敏化太阳能电池(DSSC)中使用的铂电极成本高、耐腐蚀性差的问题。本实验以木质素磺酸钠(SL)为前驱体,通过预碳化和 KOH 化学活化制备了氧氮硫(ONS)共掺木质素分层多孔碳。它的 BET 比表面积为 2252.145 m2g-1,总孔容积为 1.613 cm3g-1,并具有大量微孔、中孔和大孔。木质素分层多孔碳中ONS的总掺杂量为9.47%-14.99%。当用作 DSSC 组件中的对电极(CE)时,掺杂了 ONS 的木质素分层多孔碳的功率转换效率(PCE)达到了 8.89%,比铂电极的功率转换效率(8.14%)高出 9%。这凸显了木质素磺酸钠衍生的分层多孔碳在更具成本效益的 DSSC 中的潜在应用。
In order to address the question of high cost and poverty corrosion resistance of platinum electrodes used in dye-sensitized solar cells (DSSCs). In this experiment, sodium lignosulfonate (SL) was used as a precursor to prepare oxygen-nitrogen-sulfur (ONS) co-doped lignin hierarchical porous carbon through pre-carbonization and KOH chemical activation. It exhibits 2252.145 m2g-1 of BET-specific surface area, 1.613 cm3g-1 of total pore volume, and a profusion of micro, meso, and macropores. The total ONS doping in lignin hierarchical porous carbon is 9.47 %–14.99 %. When used as the counter electrode (CE) in a DSSC assembly, lignin hierarchical porous carbon doped with ONS achieved a power conversion efficiency (PCE) of 8.89 %, which is 9 % higher than the platinum electrode's (8.14 %) value. This highlights the potential application of hierarchical porous carbon derived from sodium lignosulfonate in more cost-effective DSSCs.
