Abstract

The invention discloses a conductive substrate of a large-area dye-sensitized solar cell, and a dye-sensitized solar cell with the conductive substrate. The conductive substrate comprises a transparent underlay, grid electrodes closely adjacent to the transparent underlay and arranged on the transparent underlay at intervals, and a conductive layer coated on the transparent underlay and coating the grid electrode, wherein the transparent underlay is a transparent substrate or a transparent polymer substrate. The width of the grid electrode is 2-100 microns and the interval between the two adjacent grid electrodes is 500-800 microns. The conductive layer is a transparent conductive layer and an ITO conductive layer, an ATO conductive layer or an FTO conductive layer is selected preferably. By distributing grid electrodes at intervals on the transparent underlay of the conductive substrate and adopting the structural design that the grid electrodes are coated by the conductive layer, the invention quickens the transmission speed of the electrons in the large-area dye-sensitized solar cell of the conductive substrate and reduces the loss of the electrons in the transmission process, thus realizing the large area and practicability of the dye-sensitized solar cell.

Description

technical field [0001] The present invention relates to a conductive substrate of a dye-sensitized solar cell and a dye-sensitized solar cell with the conductive substrate, in particular to a conductive substrate of a large-area dye-sensitized solar cell and a dye-sensitized solar cell with the conductive substrate . Background technique [0002] Dye-sensitized solar cells are a new scientific research field developed along with semiconductor electrochemistry. The dye-sensitized solar cell uses a dye-sensitized porous nanostructure film as a photoanode, and is a semiconductor photoelectric device that directly converts solar energy into electrical energy. At present, the photoelectric conversion efficiency of the reported dye-sensitized solar cells has been greatly improved, reaching 11%. This photoelectric conversion efficiency is close to the practical level. [0003] Dye-sensitized solar cells are composed of porous nanocrystalline oxide films, dye sensitizers, electro...
