Problems solved by technology

[0003] However, solar cells using crystalline silicon substrates have a problem of being difficult to popularize due to the high cost of producing crystalline silicon substrates.
On the other hand, thin-film silicon solar cells have a problem of high manufacturing costs because of the need to use various gases for semiconductor manufacturing and complicated equipment in the manufacturing process.
Therefore, at present, in any form of solar cells, the problem of rising manufacturing costs cannot be solved.

Abstract

In a wet type solar battery module (1), two or more photoelectric conversion elements (30) are arranged with a separation and are gripped between a first insulating substrate (10) and a second insulating substrate (20). In the photoelectric conversion elements (30), a first electrode (11), a photoelectric conversion section (40) and a second electrode (21) are successively laminated on the first insulating substrate (10), in this order. Either of the first electrode (11) and the second electrode (21) contained in the photoelectric conversion elements (30) has a through-passage section (50). An inter-cell insulating section (15) is provided passing through the through-passage section (50), between the photoelectric conversion sections (40) of two adjacent photoelectric conversion elements (30).; A carrier transport section (8) is provided in the space enclosed by the first insulating substrate (10), second insulating substrate (20) and inter-cell insulating section (15).

Description

technical field [0001] The present invention relates to a wet solar cell module, and particularly relates to a wet solar cell module excellent in durability. Background technique [0002] A solar cell that directly converts sunlight energy into electrical energy has attracted attention in recent years as a next-generation energy source that replaces fossil fuels because it places less burden on the global environment. Among solar cells currently in practical use, two types of solar cells, ie, a solar cell using a crystalline silicon substrate and a thin-film silicon solar cell, are the mainstream. In both types of solar cells, efforts have been made to reduce the cost of average power generation output by increasing the efficiency of photoelectric conversion. [0003] However, solar cells using crystalline silicon substrates have a problem of being difficult to popularize due to the high cost of producing crystalline silicon substrates. On the other hand, since thin-film s...
