Description

technical field [0001] The invention belongs to the field of preparation of dye-sensitized solar cell materials, in particular to a method for preparing dye-sensitized nanocrystalline semiconductor solar cell photoanode by electrospinning. Background technique [0002] Since Swiss scientist Grtzel reported the research work of dye-sensitized nanocrystalline semiconductor solar cells in 1991, it has become the most promising new type of solar cells due to its high efficiency and low cost. Its highest efficiency can reach more than 10%. Such a high efficiency is attributed to the dye sensitization effect on the one hand, and the application of the porous nanocrystalline semiconductor film as a photoanode in the battery on the other hand. This photoanode is one of the main components of dye-sensitized nanocrystalline semiconductor solar cells, and its nanocrystalline porous structure has a large specific surface area (about 100m 2 / g), the porosity is high, which greatly impr...
