结题英文摘要
The new method and technique have been established for the preparation of the nanocrystalline perovskite film electrodes applicable in dye sensitized solar cells. Their band energetics, surface states, dye sensitization, charge transfer and photoelectrochemical properties have been investigated thoroughly. SrTiO3、BaTiO3 and CaTiO3 nanocrystals were synthesized. Their nanocrystalline film electrodes were prepared and properties such as grain size, crystalization, surface properties and transmittance studied. The band energetics and electron transfer were thoroughly studied with spectroelectrochemical method, and many important results have been achieved. The novel nanocrystalline perovskite film electrodes applicable in dye sensitized solar cells were developed. The adsorption of dye, electron transfer and photoelectrochemical properties were investigated. The important results can also find application in related fields such as hydrogen generation from water.
