采用不含金属的有机染料和介孔碳气凝胶代替昂贵的铼基敏化剂和铂电极，设计并制备了低成本的准固态染料敏化太阳能电池（DSSC）。将静电纺丝的TiO 2纳米棒加入到聚偏氟乙烯（PVDF）溶液中形成三维网络纳米复合凝胶电解质。凝胶电解质中TiO 2纳米棒的存在明显提高了DSSC的离子电导率，降低了DSSC的电荷转移电阻。详细研究了凝胶电解质和碳气凝胶对电极的电化学和光伏性能的影响。特别地，具有纳米复合凝胶电解质和碳气凝胶对电极的优化DSSC在100 mW cm-2的光强度下提供6.20%的功率转换效率（PCE）。
Low-cost quasi-solid-state dye-sensitized solar cells (DSSCs) are designed and fabricated by using a metal-free organic dye and a mesoporous carbon aerogel instead of expensive ruthenium-based sensitizers and Pt electrode. The electrospun TiO2nanorods are added into a polyvinylidene fluoride (PVDF) solution to form a 3D network nanocomposite gel electrolyte. The presence of TiO2nanorods in the gel electrolyte obviously increases the ionic conductivity and decreases charge-transfer resistance of the DSSC. The effects of the gel electrolyte and the carbon aerogel counter electrode on electrochemical and photovoltaic properties have been investigated in detail. Particularly, an optimized DSSC with a nanocomposite gel electrolyte and a carbon aerogel counter electrode affords a power conversion efficiency (PCE) of 6.20% at a light intensity of 100 mW cm−2.
