摘要：

The photoelectrochemical properties of RuL2(NCS)(2) dye-sensitized nanocrystalline SnO2:TiO2 coupled and composite solar cells are reported. The coupled (bilayer) system shows higher incident photon-to-current conversion efficiency (IPCE) value than the composite (mixture) system. A maximum IPCE value attained 82.4% at 530nm wavelength in the coupled system with 3.5 mum-thick SnO2, and 7 mum-thick TiO2. The higher IPCE value in the coupled system is attributed to the promotion of the charge separation by fast electron transfer process in the SnO2/TiO2/RuL2(NCS)(2) system with different energy levels, different conduction band edge energy positions.
