Abstract
Provided is a dye-sensitized photoelectric conversion element provided with at least one dye-sensitized photoelectric conversion cell. The dye-sensitized photoelectric conversion cell in this dye-sensitized photoelectric conversion element is provided with: a first electrode substrate provided with a transparent substrate, and a transparent conductive film provided on the transparent substrate; asecond electrode which faces the first electrode substrate; an oxide semiconductor layer provided to the first electrode substrate or the second electrode; a photosensitized dye adsorbed on the oxidesemiconductor layer; and an electrolyte provided between the first electrode substrate and the second electrode. The first electrode substrate is further provided with an ultraviolet absorption layer.The transmittance TA(%) of the electrolyte at a wavelength corresponding to the band gap of the oxide semiconductor forming the oxide semiconductor layer, and the transmittance TB(%) of the first electrode substrate at said wavelength satisfy formula (1), namely 0.01*TA*TB*42, and formula (2), namely 3.5<=TB<=70.
Description
technical field [0001] The invention relates to a dye-sensitized photoelectric conversion element. Background technique [0002] The dye-sensitized photoelectric conversion element was developed by Graetzel in Switzerland, etc. It has the advantages of high photoelectric conversion efficiency and low manufacturing cost, so it is a new generation of photoelectric conversion element that has attracted much attention. [0003] The dye-sensitized photoelectric conversion element generally has at least one dye-sensitized photoelectric conversion unit, and the dye-sensitized photoelectric conversion unit includes a first electrode substrate having a transparent substrate and a transparent conductive film provided on the transparent substrate, and a first electrode substrate opposite to the first electrode substrate. The second electrode provided, the oxide semiconductor layer provided on the first electrode substrate or the second electrode, and the photosensitizing dye adsorbed o...
