Abstract

Porous titania nanohybrids (NHs) were successfully prepared by hybridizing the exfoliated titania nanosheets with anatase TiO2 nanoparticles. Various characterizations revealed that the titania NHs as photoanodes play a trifunctional role (light harvesting, dye adsorption, and electron transfer) in improving the efficiency (η) of the dye-sensitized solar cells. The optimized photoanode consisting layered NHs demonstrated a high overall conversion efficiency of 10.1%, remarkably enhanced by 29.5% compared to that (7.8%) obtained from the benchmark P25 nanoparticles under the same testing conditions.

摘要

多孔二氧化钛纳米杂化材料（NHs）是通过将剥离的二氧化钛纳米片与锐钛矿 TiO2 纳米颗粒杂交成功制备的。各种特性表明，作为光阳极的二氧化钛 NHs 在提高染料敏化太阳能电池的效率（η）方面发挥了三重功能（光捕获、染料吸附和电子转移）。由层状 NHs 组成的优化光阳极表现出 10.1%的高总转化效率，与相同测试条件下基准 P25 纳米颗粒获得的 7.8%相比，显著提高了 29.5%。
