文摘
- •
The origin of high open-circuit voltage in solid state dye-sensitized solar cells with PEO-based polymer electrolyte has been firstly unveiled.
- •
New quantitative analysis of TiO2 conduction band shift was introduced by measuring the change in the Fermi voltage with varying the concentration of the salts.
- •
PEO containing the EO groups captured cations in electrolyte and also coordinatively adsorbed on the surface of the TiO2 layer.
