Stable dye-sensitized solar cells based on organic chromophores and ionic liquid electrolyte

Stable dye-sensitized solar cells based on organic chromophores and ionic liquid electrolyte

A series of polyene–diphenylaniline based organic dyes (coded as D5, D7, D9 and D11) have been reported for the application in ionic liquid electrolyte based dye-sensitized solar cells. The effects of substitution of organic dyes on the photovoltaic performance have been investigated, which show addition of methoxy groups on the triphenylamine donor group increases short-circuit current, open-c...

Dye-sensitized solar cells with electrolyte based on a trimethoxysilane-derivatized ionic liquid

A trimethoxysilane derivative of propylmethylimidazolium iodide has been synthesized and presented for the first time. When mixed with iodine, it can be used as gel electrolyte in dye-sensitized solar cells offering through sol–gel condensation practically solid-state devices with satisfactory overall efficiency which was estimated at 3.2%. The specific conductivity of the gel electrolyte was i...

Ionic Liquid Based Electrolytes for Dye-Sensitized Solar Cells

1.1 New type of solar cell: dye-sensitized solar cells (DSSCs) The rising price of fossil fuels, together with their rapid depletion and the pollution caused by their combustion, is forcing us to find sources of clean renewable energy. Fortunately, the supply of energy from the sun to the earth is gigantic, i.e., 3 × 1024 joule a year or about ten thousand times more than what mankind consumes ...

Synthesis of Organic Chromophores for Dye Sensitized Solar Cells

Synthesis and Application of Two Organic Dyes Based on Indoline in Dye-Sensitized Solar Cells

In this paper we sensitized two new organic days dye 1 and dye 2 based on thioindigo with phenothiazine as the electron donor group. We used acrylic acid and cyanoacrylic acid as the electron acceptor anchoring group in dye 1 and dye 2 respectively. The proposed dyes were sensitized from phenothiazine as the starting material by standard reactions and characterized by different techniques such ...
