基于锐钛矿相二氧化钛溶胶的高效染料敏化太阳能电池
High Efficiency Dye-Sensitized Solar Cells Based on the Anatase TiO2 Sols
摘要
Abstract
TiO2 precipitates were treated with dilute HNO3 solution or H2O2 solution, anatase TiO2 sols and peroxotitanium acid (PTA) solution were obtained, respectively. Both anatase TiO2 sols and PTA solution were subjected to further hydrothermal treatment, and TiO2 nanorod sols with a specific surface area of more than 100m2/g were formed via the oriented attachment mechanism. The anatase nanorods were used to fabricate dye-sensitized solar cells (DSSCs), and cells with a higher open-circuit voltage were observed. The anatase nanorod sols were also used to make compact layers over FTO conductive glass, and infiltrated into porous TiO2 layers using Degussa P25 titania as raw material by doctor-blade technique to elimination large pores and defects in DSSCs anodes. The sols treated anodes were sintered and assembled into DSSCs, and the photoelectric conversion efficiency of resulted DSSCs increased from 4.15% to 5.63% under AM1.5 simulated solar irradiation.关键词
