Abstract

The invention discloses a dye sensitized solar cell, which comprises an optical anode, a counter electrode, electrolyte and a packaging shell. The counter electrode is positioned above the optical anode and is arranged inside the packaging shell; the electrolyte is full of the packaging shell; the optical anode comprises a transparent conductive substrate, a transparent conductive film and a porous transition metal oxide film which adsorbs dye molecules; the porous transition metal oxide film is coated on the transparent conductive film; and the counter electrode comprises a diaphragm serving as a substrate of the counter electrode, and a catalytic material and a grid electrode which are deposited on the diaphragm in turn. The invention also discloses a method for preparing the dye sensitized solar cell. The invention reduces the manufacturing cost, lightens the cell weight, reduces the short circuit risk and shortens the electronic transmission distance, and the dye sensitized solar cell is high-efficiency.

Description

technical field

[0001] The invention relates to a solar cell and a preparation method thereof, in particular to a structural design, preparation and packaging method of a novel dye-sensitized solar cell. Background technique

[0002] Nanocrystalline dye-sensitized solar cell (DSC) is a semiconductor optoelectronic device that directly converts solar energy into electrical energy based on the principle of photovoltaics, using a dye-sensitized porous nanostructured film as a photoanode. It is developed along with the development of semiconductor electrochemistry. A new field of scientific research. In 1991, the research team led by Professor Grötzel of the Lausanne Institute of Technology, Switzerland, used nano-TiO with a high specific surface area 2 The porous film is used as the semiconductor electrode, and the organometallic compound such as Ru is used as the photosensitizing dye, and the appropriate redox electrolyte is selected as the medium to assemble TiO 2 Nanocryst...
