Problems solved by technology

However, the conditions disclosed as the durability test are only evaluations over time at a constant temperature of 25°C, and it is considered that the evaluation of durability in an actual solar cell usage environment is insufficient.
Therefore, there are no reports on a sealant capable of passing a durability test in a high-temperature, high-humidity environment and a solar cell using the sealant

Embodiment 1

[0111] As an example of a photoelectric conversion device ( figure 1 ) shown, by screen printing machine on the conductive surface of the FTO conductive glass support as the conductive support, coated with terpineol to make paste-like TiO 2 fine particles (average particle diameter: 20 nm), and fired at 450° C. for 30 minutes to thereby form a conductive support having a semiconductor-containing layer (film thickness: 10 μm, minor axis width: 5 mm). The dye represented by formula (1) is 3.2×10 -4 The concentration of M was dissolved in a 1:1 mixed solvent of acetonitrile and tert-butanol; and the conductive support provided with the semiconductor-containing layer obtained above was immersed in a dye solution for 48 hours at room temperature to thereby fabricate an oxidized material semiconductor electrodes. Then, similarly on the conductive surface of the FTO conductive glass support with Pt was vapor-deposited to thereby fabricate a counter electrode.

Abstract

Disclosed is a photoelectric conversion element which comprises: a first conductive supporting body that has a semiconductor-containing layer; a second conductive supporting body that has a counter electrode which is arranged at a position where the counter electrode faces the semiconductor-containing layer at a predetermined distance; a charge transfer layer that is held in a space between the first and second conductive supporting bodies; and a sealing agent that is provided in the peripheral portions of the first and second conductive supporting bodies so as to seal the charge transfer layer. The photoelectric conversion element is characterized in that the sealing agent is a thermosetting sealing agent for a photoelectric conversion element, said thermosetting sealing agent containing (a) an epoxy resin and (b) at least one heat curing agent that is selected from the group consisting of aromatic hydrazides and aliphatic hydrazides having 6 or more carbon atoms.

Description

technical field [0001] The present invention relates to a photoelectric conversion device using a thermosetting photoelectric conversion device sealant containing an epoxy resin and a specific curing agent, and particularly relates to excellent adhesion and moisture resistance even under high-temperature and high-humidity environments Reliable high-reliability photoelectric conversion device. Background technique [0002] Although solar cells attracting attention as clean energy have been used in general houses in recent years, they have not yet spread sufficiently. Reasons include, for example, that the performance of the solar cell itself cannot be said to be good enough, the inevitable need to make the module large, and low productivity in module manufacture, resulting in high cost. [0003] It is generally constructed by protecting a photoelectric conversion material such as silicon, gallium-arsenic, or copper-indium-selenium with an upper transparent protective materia...
