Conductive substrate of large-area dye-sensitized solar cell and solar cell thereof

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.

Problems solved by technology

The main reason for the above changes is the influence of the surface resistance of the conductive glass, that is, the transmission distance of electrons is too long, which leads to an increase in the loss of electrons during transmission.
