[0063] Example: Fabrication of Dye-Sensitized Solar Cells Using Platinum Ink for Inkjet Printing

[0064] By dissolving 0.99 g of platinum chloride (H 2 PtCl 6 ) to prepare a platinum chloride solution, and a polyvinylpyrrolidone (PVP) solution was prepared by dissolving 0.13 g of polyvinylpyrrolidone in 10 ml of ethylene glycol. Then, the platinum chloride solution was added dropwise to the PVP solution at 110°C.

[0065] Subsequently, the resulting mixture was reacted for 3 hours, and 50 ml of ethanol was added and evaporated, thereby preparing a platinum ink containing platinum nanoparticles.

[0066] The platinum ink thus prepared was a composition including 17 wt% of platinum nanoparticles, 80 wt% of ethylene glycol, and 3 wt% of PVP.

[0067] Then, the prepared platinum ink was coated on one side of the curved glass substrate coated with fluorine-doped tin oxide (FTO) by using an inkjet device. The coated platinum ink was heated at 100° C. for 1 hour and sintered at ...

Abstract

The present invention provides an electrode composition for inkjet printing, which can be used to form an electrode having a uniform thickness on a curved substrate by inkjet printing, and a method for manufacturing an electrode for a dye-sensitized solar cell using the same. In particular, the present invention provides an electrode composition for inkjet printing, the electrode composition including about 10 to 40 wt % of platinum nanoparticles, about 1 to 10 wt % of polymer surface stabilizer, and about 40 to 89 wt % of solvent.

Description

technical field [0001] The present invention relates to electrode compositions and methods of using the same to make electrodes for dye-sensitized solar cells. More particularly, the present invention relates to an electrode composition for inkjet printing, which can be used to form an electrode having a uniform thickness on a curved substrate by inkjet printing. Background technique [0002] With increasing concerns about global warming, technologies for supplying and using environmentally friendly energy sources have gained a great deal of public attention. An attractive field, in particular, is solar cells using new and renewable energy sources. [0003] Examples of such solar cells include silicon-based solar cells, using inorganic substances such as copper indium gallium selenide (Cu(InGa)Se 2 , CIGS) thin-film solar cells, dye-sensitized solar cells, organic solar cells, organic-inorganic hybrid solar cells, etc. [0004] Among these various types of solar cells, dy...
