Problems solved by technology

Resin bonding strength is low at low temperature, and there are other disadvantages such as poor operability, poor wear resistance and low elastic recovery, which makes the durability of solar cells poor for long-term use
[0010] As described above, the proposed sealant cannot satisfy all the properties required as a sealant for photoelectric conversion devices, especially dye-sensitized solar cells
In particular, commonly used sealants do not have the properties to seal the redox charge transfer layer

Embodiment 1

[0114] Compounds having a glycidyl structure (bisphenol A epoxy resin (RE-301S, manufactured by NipponKayaku Co., epoxy equivalent 182 g / eq, 30 parts by weight; and Epomic R301, manufactured by Mitsui Chemical Co., epoxy Equivalent 500g / eq, 10 parts by weight), a compound with an oxane structure (Celoxide2021A, manufactured by Daicel Chemical Industries, Ltd., 30 parts by weight), a compound with an oxetane structure (BPDO (biphenyldioxane Cyclobutane, manufactured by Ube Industries, Ltd.), 30 parts by weight), and a silane coupling agent (epoxysilane, Saila Ace S510, by Chisso Co., 1 part by weight), and heated at 70° C. The cooling After the mixture reaches room temperature, in the dark, add 3 parts by weight of diaryliodonium salt (represented by Chemical Formula 1, Rhodorsil photoinitiator 2074, manufactured by Rhodia Chimie Co.) as a cationic polymerization initiator, and 2 parts by weight of diaryliodonium Ethylthioxanthone (represented by the following Chemical Formula ...

Embodiment 2

[0118] According to the same method as in Example 1, the sealant (B) for photoelectric conversion devices of the present invention is obtained, the viscosity of which is about 50,000 Pa·s, the difference is that bisphenol A with an epoxy equivalent of about 250g / eq is used Epoxy resin and xylylenedioxetane (trade name XDO, manufactured by Toa Gosei Co.) were substituted for RE-301S and BPDO, respectively.

Embodiment 3

[0120] According to the same method as in Example 1, the sealant (C) for photoelectric conversion devices of the present invention is obtained, and its viscosity is about 50,000 Pa·s. The difference is that the hydrogenated product of bisphenol A epoxy resin (Adeca ResinEP 4080, manufactured by Asahi Denka Co.) was substituted for Celoxide 2021A.

Abstract

A sealing agent for a photoelectric conversion element which comprises one or more of a compound having a glycidyl structure, a compound having a cyclohexene oxide structure, a compound having an oxetane structure and a compound having a vinyl ether structure, and a cationic polymerization initiator; a photoelectric conversion element using the sealing agent; and a solar cell comprising the photoelectric conversion element. The sealing agent for a photoelectric conversion element can be used for pasting together upper and lower electroconductive glass substrates at an ordinary temperature in the manufacture of a photoelectric conversion element, and is excellent with respect to adhesion strength and the reliability in moisture resistance.

Description

technical field [0001] The invention relates to a sealant, in particular to a sealant for a photoelectric conversion device, and to a photoelectric conversion device made using the sealant and a manufacturing method thereof. The present invention also relates to a solar cell using such a photoelectric conversion device. Background technique [0002] Although solar cells introduced as clean energy have been used in household power sources in recent years, solar energy in households has not yet spread sufficiently. The reason is that the performance of the solar cell itself is insufficient, resulting in a large module size, low productivity, and a high price of the solar cell due to these disadvantages. [0003] Assemble solar cell modules by protecting photoelectric conversion devices such as monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium-arsenic or copper-indium-selenium with upper transparent protective material and lower substrate protective ...
