High Power Output of Solid-state Dye-sensitized Solar Cells with Strongly Basic Pyridine Compounds under Low-intensity Illumination

We investigated the introduction of basic strong pyridine compounds into the hole-transporting layer in solid-state dye-sensitized solar cells to obtain a good power output under low-intensity illumination. It was found that the ionization potential of the hole-transporting layer was shifted by the...

Description
Summary:We investigated the introduction of basic strong pyridine compounds into the hole-transporting layer in solid-state dye-sensitized solar cells to obtain a good power output under low-intensity illumination. It was found that the ionization potential of the hole-transporting layer was shifted by the basicity of pyridine compounds, an especially large shift of the ionization potential was obtained by strongly basic pyridine compounds.
