TANDEM METAL OXIDE SOLAR ELEMENT Russian patent published in 2017 - IPC H01L31/42 H01G9/20 

FIELD: physics.

SUBSTANCE: tandem metal oxide solar element comprises two metal oxide solar elements (MO SEs) located one below the other in the course of the light flux, based on mesoscopic layers of sensitized metal oxide having a common intermediate current collector contact, according to the invention, the common intermediate current collector contact is located on a glass substrate located between the upper and lower MO SE light flux in the direction of the light flux of the solar element, to which, from the side facing the upper MO SE of the light flux, a platinum driving layer that is a counterelectrode for the upper MO SE, and a conductive coating of tin oxide doped with fluorine or indium is located on the opposite side of the glass substrate facing the downstream light of the MO SE, and on the opposite side of the glass substrate facing the bottom in the course of the light flux of MO SE, conductive coating of tin oxide is deposited doped with fluorine or indium, which serves as a conductive electrode to the lower MO SE. The upper MO SE in the course of the light flux is sensitized with an organic dye absorbing sunlight in the wavelength range of 400-650 nm, and the lower MO SE in the course of the light flux is sensitized with an organic dye absorbing sunlight in the wavelength range of 650-1000 nm.

EFFECT: increasing the efficiency and optimizing the operation of the solar element for both high and low light flux intensities.
