Abstract

A conductive glass of a dye-sensitized solar cell comprises a conductive glass layer, the upper surface of the conductive glass layer is provided with a low-resistance grid electrode and a compact titanium dioxide barrier film layer sequentially from bottom to top, and the compact titanium dioxide barrier film layer isolates the low-resistance grid electrode from the external environment; the performance of the cell is proximate to the performance of a small area cell, and the low-resistance grid is unlikely to be oxidized and corroded by electrolytic solution; meanwhile the technique is simple, and the cost is low; the conductive glass is applicable to large area dye-sensitized solar cell.

Description

1. Technical field [0001] The invention belongs to the technical field of conductive glass technology, in particular to a conductive glass suitable for large-area dye-sensitized solar cells. 2. Background technology [0002] Dye-sensitized solar cells are a new type of amorphous silicon solar cells, which have the advantages of being cheaper and more environmentally friendly than silicon solar cells, but because the photoanode is completely exposed to the electrolyte, Ti0 2 and the photogenerated electrons on the conductive glass substrate will interact with the I in the electrolyte 3 - Recombination occurs to form a dark reaction, thereby reducing the photoelectric conversion efficiency. At the same time, as the battery area gradually increases, the volt-ampere characteristics of the battery have changed significantly. Compared with the small battery, the fill factor and photoelectric conversion efficiency are greatly reduced. Mainly The reason is the effect of the surfac...
