Problems solved by technology

[0004] However, the existing positive electrode of solar cells is generally only made of TiO 2 The structure of the thin film layer only converts solar energy into electrical energy output, and the entire solar cell only shows the conversion of light energy into electrical energy, and the storage of electrical energy is only a single-function energy storage device or a third electrode, which makes the structure of the solar cell complex. Large size, inconvenient for general application

Abstract

The invention discloses an energy storage photosensitive solar energy cell anode and a preparation method thereof. A structure of the energy storage photosensitive solar energy cell anode comprises a conductive glass substrate, a photoelectric conversion layer contacting with a conductive surface of the conductive glass substrate and an electric storage layer contacting with the photoelectric conversion layer. Nanometer TiO2 added drop by drop with an adhesive is grinded to a sticky state, is then coated on the conductive surface of the conductive glass substrate, is then dried, is then immersed in photosensitive dye for 12-24 hours and is then dried to form the photoelectric conversion layer; charcoal aerogel added drop by drop with an adhesive is grinded to a sticky state, is then coated on the photoelectric conversion layer and is then dried to form the electric storage layer; and the conductive glass substrate coated with the photoelectric conversion layer and the electric storage layer is baked at temperature of 130 DEG C for half an hour to form the energy storage photosensitive solar energy cell anode. The energy storage photosensitive solar energy cell anode has uniform coating, and an energy storage photosensitive solar energy cell assembled by the energy storage photosensitive solar energy cell anode has relatively good photoelectric conversion and energy storage capabilities.

Description

technical field [0001] The invention relates to a solar cell positive electrode and a preparation method thereof, in particular to an energy storage photosensitive solar cell positive electrode and a preparation method thereof, and belongs to the field of energy technology. Background technique [0002] With the increasing energy and environmental crisis, seeking new renewable energy sources is becoming an urgent problem to be solved. Several studies have been conducted with the aim of developing alternative energy sources that can replace conventional fossil fuels and address the looming energy crisis. Solar energy is inexhaustible, and it is green and renewable. [0003] Dye-sensitized solar cells are electrochemical solar cells, which are mainly composed of photosensitive dye molecules that absorb sunlight and generate electron-hole pairs, and transition metal oxides that transmit the generated electrons. [0004] However, the existing positive electrode of solar cells ...
