Transparent polyaniline counter electrode-base two-sided dye-sensitized solar cell as well as preparation method and application thereof

Abstract

The invention provides a transparent polyaniline counter electrode-base two-sided dye-sensitized solar cell as well as a preparation method and an application thereof. The method for preparing the two-sided dye-sensitized solar cell comprises the steps of: using an aniline monomer to form a transparent polyaniline counter electrode on a fluorine-doped tin oxide (FTO) or indium tin oxide (ITO) conductive glass matrix modified by 4-amino thiophenol by electrochemical or chemical polymerization, and then carrying out a light splitting design. The invention fully utilizes the light transmittance, the electrical conductivity and the electro-catalysis of the polyaniline counter electrode, and adopts the reasonable light splitting design to divide one beam of sunlight into two beams of light sources which vertically enter a photo-anode and the counter electrode; the polyaniline counter electrode is good in light transmittance, high in electrical conductivity and excellent in electro-catalysis activity; the preparation method is convenient and easy to perform, low in cost and large in improvement space; and the assembled two-sided dye-sensitized solar cell is high in dye excitation rate, high in excitation electron density and high in photoelectric conversion efficiency.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and in particular relates to a double-sided dye-sensitized solar cell based on a polyaniline transparent counter electrode base and a preparation method and application thereof. Background technique [0002] Dye-sensitized solar cells are a kind of titanium dioxide photoanode, sensitizing dye, I - / I 3 - An electrochemical device that converts solar energy into electrical energy consisting of an electrolyte and a counter electrode. [0003] In 1991, the Gr?tzel research group of the Institute of Advanced Technology in Lausanne, Switzerland used nanoporous titanium dioxide as a semiconductor anode, and Ru complexes as sensitizing dyes. I - / I 3 - As a redox electrolyte, platinum was used as the counter electrode to assemble a prototype of a dye-sensitized solar cell, and its photoelectric conversion efficiency was 7.1%, which opened the prelude to the research on dye-sensitized s...
