PHOTOCHEMICAL METHOD FOR CONVERTING ELECTROMAGNETIC RADIATION INTO ELECTRICAL ENERGY Russian patent published in 2021 - IPC H01L31/04 H01L51/46 

FIELD: chemistry.

SUBSTANCE: invention relates to the conversion of electromagnetic radiation into electrical energy in a wide spectrum of wavelength ranges from microwave to ultraviolet range and can be used for the manufacture of photovoltaic batteries of the electrochemical type, on the basis of which autonomous power supplies of electrical energy for various power ranges can be developed. In the electrochemical method for converting electromagnetic radiation into electrical energy according to the invention, a heteropoly acid series 2-18 having the chemical formula H₁₅[P₂W₉V₉O₆₂] is used as the main reagent, at the same time, according to the proposed method, a 10-25% aqueous solution 2 of heteropolyacid H₁₅[P₂W₉V₉O₆₂] is prepared in oxidized form, which is poured into vessel 1 and vessel 3, and both vessels are connected to each other by a curved tube 8, then tube 8 is filled with the same solution of heteropolyacid and with the help of the same tube 8 the liquid levels in both vessels 1 and 3 are leveled, then graphite electrode 10 is lowered into vessel 3, and curved electrode 9 is lowered into vessel 1, both electrodes are connected to the electrical circuit, then the vessel 1 is irradiated from above with electromagnetic radiation 7 of natural origin from the sun or with the help of artificial emitters; to increase efficiency of the process, vessel 1 can be heated to temperatures of 25-50°С.

EFFECT: expanding the wavelength range of converting electromagnetic radiation into electrical energy, from UV to microwave range, from 180 nm to 5⋅10⁷ nm; achieving the efficiency of conversion of electromagnetic radiation into electrical energy on average not less than 92%, as well as simplifying the design and reducing the cost of the process.
