Conductive polymer-carbon-imidazolium composite: a simple means for constructing solid-state dye-sensitized solar cells.

A clay-like conductive material comprising polyaniline-loaded carbon black particles and an ethyleneoxide-substituted imidazolium iodide was prepared. The material was sandwiched between dye-coated porous TiO2 and counter-electrode to form a solid-state dye-sensitized solar cell, which works with overall conversion efficiencies of 3.48% and 4.07% for AM 1.5, 100 mW cm(-2) and 23 mW cm(-2) irradiation, respectively.

A high-voltage dye-sensitized photocapacitor of a three-electrode system.

A high-voltage photo-rechargeable capacitor (photocapacitor) of three-electrode configuration, comprising a dye-sensitized mesoporous TiO2 electrode, two carbon-coated electrodes, and two liquid electrolytes, attained a charge-state voltage of 0.8 V and high energy density per area of 47 microW h cm(-2) which is five times larger than the previous two-electrode photocapacitor.

A solid-state dye-sensitized photovoltaic cell with a poly(N-vinyl-carbazole) hole transporter mediated by an alkali iodide.

A polymer-based dye-sensitized solar cell in dry solid state was constructed using poly(N-vinyl-carbazole)(PVK) as a hole-transporting layer; the cell attained the highest power efficiencies of 2.4% and 2.0% at 1/4 sun and 1 sun (AM1.5), respectively, by incorporation of a solid intermediate layer (LiI, KI) at the dye-PVK interface.
