TANDEM SOLAR PHOTOCONVERTER Russian patent published in 2014 - IPC H01L31/04 B82B1/00 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of solar photovoltaic energetics, in particular, to devices for direct conversion of solar energy into electric one. A tandem solar photoconverter is proposed, comprising two solar elements arranged under each other, the upper of which is a metal oxide solar element on the basis of a mesoscopic layer of a sensitised metal oxide, and the lower one - a solid-state solar element. The mesoscopic layer of the sensitised metal oxide of the upper solar element has a thickness of 5.0-5.5 mcm, and the lower solid-state solar element in the photoconverter is a solar element based on mono- or multicrystalline silicon, at the same time the difference of voltage values of idle running of the upper and lower solar elements of the photoconverter does not exceed 0.1 V, and the mode of parallel electric connection of the upper and lower SE to the load is realised. The mesoscopic layer of the sensitised metal oxide is represented by nanocrystalline metal oxides selected from the group: titanium dioxide, zinc oxide, nickel oxide, iron oxide or their mixtures.

EFFECT: proposed tandem solar PC realises direct conversion of light energy into electric one regardless of the intensity of solar radiation and angle of light falling and provides for an increased efficiency of conversion of light energy into electric one, also under conditions of low and diffused illumination.
