Embodiment Construction

[0020] Specific embodiments of the present invention will be described in detail below in conjunction with technical solutions and accompanying drawings.

[0021] This embodiment adopts stacked dye-sensitized solar cells with two different structures, as shown in the accompanying drawings. The two-layer structure includes an electrode substrate 1, a semiconductor photoanode 2 adsorbed with visible light dyes, a semiconductor photoanode 3 adsorbed with near-infrared dyes, a counter electrode 4 and a solar cell electrolyte 9. Wherein the conductive substrate is plastic film or conductive glass. The semiconductor film is made of semiconductor oxides such as titanium dioxide or zinc oxide. A layer of dye is adsorbed on the semiconductor thin film electrode. The dyes used in the two photoanodes constituting the laminated solar cell can be the same or different, and the dye used in the upper solar cell is a visible light dye. In the second laminated solar cell, the dye used is a ...

Abstract

The invention relates to a device for producing hydrogen and oxygen through photoelectrochemistry composite or coupling, and a method thereof, which belongs to the technical field of green renewable energy. The device is characterized by comprising a solar battery at the upper part and a photoelectrochemistry pool at the lower part; the solar battery at the upper part comprises an electrode base plate, a photo-anode, electrolyte and a counter electrode; the solar battery at the upper part is a silicon solar battery, a dye-sensitized solar battery, an organic solar battery, a chemical compound semi-conductor solar battery or a polymer solar battery and the like; the photoelectrochemistry pool at the lower part comprises a photo-anode, electrolyte and a counter electrode. During use, under the irradiation of sunlight or simulated sunlight, the solar battery at the upper part discharges and generates external bias voltage, and the photo-anode of the photoelectrochemistry pool generates potential or energy. The external bias voltage and the potential or energy generated by the photo-anode of the photoelectrochemistry pool reach the schizolysis energy of water in the photoelectrochemistry pool, and the electrodes respectively generate hydrogen and oxygen. The device is characterized by high conversion efficiency of solar energy and hydrogen energy, low cost, simple process, and easy mass production of hydrogen.

Description

technical field [0001] The invention belongs to the technical field of green and renewable energy, and relates to a photoelectrochemical compound or coupling system device using solar cells and a method for producing hydrogen and oxygen with high efficiency, low cost, green and environmental protection. Background technique [0002] In order to solve the problems of energy shortage and global warming, the development and utilization of green renewable energy has become a major issue facing human beings. Hydrogen energy has become the most promising new energy due to its cleanliness, high efficiency, high calorific value, and environmental friendliness. It can change the current situation of relying mainly on fossil energy and meet the needs of future energy development. There are many ways to produce hydrogen, but currently fossil fuel hydrogen production accounts for more than 90% of the total. requirements for sustainable development. Hydrogen production from solar energ...
