Embodiment 1

[0150] A 20% by weight Nafion dispersion was neutralized with an aqueous lithium hydroxide solution obtained by dissolving lithium hydroxide monohydrate in ion-exchanged water, and a 5% by weight Nafion dispersion was prepared using ion-exchanged water. 1.8 parts by weight of titanium oxide particles A and 2 parts by weight of isopropanol were added to 6 parts by weight of the 5% by weight Nafion dispersion, followed by dispersion treatment with an ultrasonic homogenizer to obtain a separator ink.

Embodiment 2

[0152] A separator ink was obtained in the same manner as in Example 1 except that 1.8 parts by weight of silica nanoparticles was used instead of 1.8 parts by weight of titanium oxide particles A in Example 1.

Embodiment 3

[0154] A separator ink was obtained in the same manner as in Example 1 except that 1.8 parts by weight of alumina-coated titanium oxide particles was used instead of 1.8 parts by weight of titanium oxide particles A in Example 1.

Abstract

Provided is a separator composition capable of forming a separator which can improve the photoelectric conversion efficiency of photoelectric conversion devices, such as dye-sensitized solar cells, without firing. A separator composition is prepared, containing an ionic polymer and at least one kind of non-conductive particles selected from the group consisting of polymer particles and ceramic particles, wherein the proportion of the ionic polymer is 0.1-30 parts by weight with respect to 1 part by weight of the non-conductive particles. The composition may be coated onto a support to prepare a membrane-like separator without sintering. The non-conductive particles may be insulating inorganic oxide particles. A laminate may be produced by laminating a photoelectric conversion layer 2 on a conductive substrate 1 and laminating the membrane-like separator 3 on the photoelectric conversion layer, and a photoelectric conversion device may be manufactured using the laminate.

Description

technical field [0001] The present invention relates to a composition for a separator constituting a photoelectric conversion element such as a solar cell (especially a dye-sensitized solar cell), a separator formed from the composition, a method for producing the same, and a use thereof. Background technique [0002] A photoelectric conversion element such as a dye-sensitized solar cell generally adopts an opposed single cell. Electrodes (counter electrodes), and electrolyte solution sandwiched between these electrodes and sealed. The electrolytic solution is usually enclosed in a space or void formed by sandwiching and sealing a separator (or spacer) between the edges of both electrodes. [0003] As a dye-sensitized solar cell element having such a separator, for example, Japanese Patent No. 6143911 (Patent Document 1) discloses a dye-sensitized solar cell comprising: A first electrode of a transparent conductive film on one side of the substrate, a second electrode faci...
