在染料敏化太阳能电池(DSCs)中，铂负载量约为10wt%的铂/碳化硅纳米复合材料作为对电极，其功率转换效率(PCE)高达7.07%(含SIC CE的DSC的PCE为3.29%)，达到了铂对电极的98.5%(7.18%)。这项工作为开发低成本的铂负载复合电池提供了有力的支持。铂/碳化硅的使用有望减少DSCs对铂的依赖，同时也有望用于控制铂含量和防止铂纳米颗粒聚集所需的许多化学和电化学过程。
A Pt/SiC nanocomposite with ~10 wt% Pt loading was used as a counter electrode (CE) in dye-sensitized solar cells (DSCs), it shows a high power conversion efficiency (PCE) of 7.07% (a DSC with a SiC CE has a PCE of 3.29%), reaching 98.5% of the level obtained using a Pt CE (7.18%). This work provides substantial support for developing low-cost Pt-loaded composite CEs for DSCs. Pt/SiC use is expected to reduce the dependence on the Pt in DSCs, while it can also be expected to be used in many chemical and electrochemical processes required to control the amount of Pt and prevent Pt nanoparticle aggregation.
