摘要：

The photoelectrochemical properties of the mercurochrome-sensitized SnO2/TiO2 coupled cell were studied with TiO2 film thickness at a constant SnO2 thickness. The optimal film thickness in the coupled cell is 3.5-mum-thick SnO2 and 6-7-mum-thick TiO2 and the maximum incident photon-to-current conversion efficiency (IPCE) value reached about 30.5% at 520 nm. The higher IPCE value in the 3.5 mum SnO2/6-7 mum TiO2 coupled cell is attributed to a better charge separation by fast electron transfer process from excited dye to TiO2 to SnO2.
