固态染料敏化二氧化钛纳晶薄膜太阳能电池的研究进展

固态染料敏化太阳能电池是目前能源研究的热点领域之一。我们设计并合成了一系列含有不同特性基团(如柔软的高分子链、可现场固化基团和高电导的离子液体基团)的高分子固态电解液应用于染料敏化太阳能电池;同时,结合理论模拟计算得出的二氧化钛纳晶薄膜工作电极和对电极的光散射效应与光限域效应能提高电池的光吸收效率,二氧化钛纳晶薄膜孔隙率的增大能增加固态电解液在膜内的渗透和扩散,对工作电极和对电极进行结构优化可得到高光电转换效率的固态染料敏化太阳能电池。

Research Progress of Solid State Dye-sensitized TiO2 Nanocrystalline Thin Film Solar Cells

Solid state dye-sensitized solar cells(DSSC) have been intensively researched recently. In our group, a series of solid state polymer electrolytes of DSSCs have been designed and synthesized by introducing various functional groups, such as flexible chains, latent chemically cross-linking groups and ionic liquid group. Combining with the structural optimization of TiO2 nanocrystalline thin film electrodes and counter electrodes based on the theoretical simulation of that the efficiency of light absorption can be improved by light scattering and confinement, and the diffusion and penetration of polymer electrolyte can be enhanced by using TiO2 film with larger porosity, solid state DSSCs with high photo-electric energy conversion efficiency have been obtained.
