Abstract

The invention discloses a large-power dye-sensitized solar cell. The solar cell comprises a plurality of strip-shaped monomer dye-sensitized solar cells (DSC) that are connected in series or in parallel. The solar cell comprises an upper substrate and a lower substrate, and both of the two substrates face to each other and comprise a plurality of strip-shaped monomer cell areas; a light-anode and a counter electrode are formed on the upper substrate and the lower substrate respectively; and the dye is adsorbed on the photo-anode. The upper substrate and the lower substrate are sealed by glass dust of low melting point or epoxy resin; furthermore, the glass spherules or polymer spherules with the diameter of 20-100 microns are taken as isolation materials; a space with uniform spacing is formed between the upper substrate and the lower substrate with large area; and an electrolyte is filled in the space between the upper substrate and the lower substrate. In the invention, the optical absorption efficiency is improved, the problems of the nano-material dye-sensitized solar cells of TiO2, ZnO and the like, such as bad stability, small area, bad consistency and poor repeatability of the device and the like, are solved, and the solar cell is applicable to the industrial large-scale production.

Description

technical field

[0001] The invention relates to a solar cell, in particular to a large-area, high-power dye-sensitized solar cell and a preparation and packaging method thereof. 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 Ecole Polytechnique de Lausanne, Switzerland The research team led by the professor used nano-TiO with 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 Nanocrystalline dye-sensitized solar cells w...
