Dye-sensitized solar cell module and preparation method thereof

Abstract

The invention provides a dye-sensitized solar cell module, comprising a plurality of basic cells which in physically adjacent position form cell components; the adjacent cell components are in series connection or parallel connection; the series connection between the adjacent cell components is as follows: a contact electrode is arranged on an upper substrate conducting layer of the last basic cell unit of the previous cell component; a contact electrode is arranged on an upper substrate conducting layer of the first basic cell unit of the rear cell component; the contact electrodes are bothon the edge of the substrate and the counter electrode of last basic cell unit of the previous cell component is in electrical connection with the photo-anode of the first basic cell unit of the rearcell component by the contact between the contact electrode. The invention further provides a corresponding preparation method for the cell module. The invention has simple technique and high rate offinished product, capable of realizing series and parallel connection flexibly in the cell module.

Description

technical field [0001] The invention relates to solar cell technology, in particular, the invention relates to a dye-sensitized solar cell module and a preparation method thereof. Background technique [0002] Dye-sensitized solar cells are solar cells with simple production process, low cost and environmental friendliness. Dye-sensitized solar cells generally include from bottom to top: lower substrate, lower conductive layer, lower electrode, electrolyte, upper electrode, upper conductive layer and upper substrate; the upper electrode is made of nano-semiconductor porous film adsorbed with dye, and the upper conductive layer And upper substrate and use transparent material. At present, the efficiency of small-area dye-sensitized solar cells can reach more than 11%. At the same time, because of its relatively simple manufacturing process, its cost is much lower than that of silicon-based solar cells. However, there are still some problems in its packaging technology and m...

Problems solved by technology

The problem with the W-type contact is that the photoanode and the counter electrode need to be prepared sequentially on a substrate. Since the functions of the two electrodes are just opposite, the two are likely to cause mutual contamination during the preparation process, so the process is very complicated; The photoelectric conversion efficiency generated by the incident on the electrode will be different, so there is a problem of current mismatch in the series structure of the W-type contact, resulting in additional energy loss
