Abstract

The invention is an all-solid nano crystal solar battery and making method. It smears the plasm of semiconductor nano material on the transparent base piece of the electric thin film, then making high-temperature sintering to prepare wide-band semiconductor nano crystal thin film, and then immerge in the solution to obtain sensitized dye nano crystal semiconductor electrode as anode; uses electric polymer or inorganic / electric polymer cooperative system as P-type material to smear the anode, and uses the electric base piece plated with Pt or Au as pair electrodes to compose the solar battery.

Description

technical field [0001] The invention belongs to the field of nanocrystalline solar cells, and in particular relates to an all-solid-state nanocrystalline solar cell prepared by using a conductive polymer or an inorganic / conductive polymer synergistic system as a p-type material and a preparation method thereof. Background technique [0002] Since the Swiss scientist Gratzel reported the research work of the dye-sensitized nanocrystalline solar cell in 1991, it has become the most potential new type of solar cell due to its high efficiency and cheap characteristics. Such batteries consist of nanoporous electrodes (sintered TiO 2 Semiconductor nanoparticle film), dye molecules for absorbing photons (commonly used as ruthenium complexes), electrolyte and counter electrode for reducing media. When the electrolyte is selected as containing I - / I 3 - When using acetonitrile or ethanol / propanol solution, its photoelectric conversion efficiency can reach ...
