DOUBLE-SIDED SOLAR PHOTOCONVERTER (VERSIONS) Russian patent published in 2014 - IPC H01L31/04 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of solar photovoltaic energetics, namely, to devices for direct conversion of solar energy into electric one. There are two versions proposed for a double-sided solar photoconverter (PC), comprising two identical solar elements (SE) on the basis of sensitised metal-oxide (MO) mesostructures, the illuminated surfaces of which are aligned in opposite directions. In the first version of the PC both SE are mounted on a common conducting rear contact from a flexible metal base with a conducting coating applied on its both surfaces, and upper conducting contacts represent flexible polymer transparent films with a conducting transparent coating applied onto them. In the second version of the invention both SE are mounted on a common conducting rear contact from a glass plate with a conducting coating applied on its both surfaces, and upper conducting contacts represent glass plates with a conducting transparent coating applied onto them. Sensitised MO mesostructures are applied onto the conducting transparent coating on polymer transparent films (version 1) or onto the conducting transparent coating on glass plates, used as the upper conducting contacts (version 2). As the sensitised MO mesostructures for both identical SE they use sensitised nanocrystalline metal oxides selected from the group: titanium dioxide, zinc oxide, nickel oxide, iron oxide or their mixtures.

EFFECT: proposed PC provides for direct conversion of light energy into electric one with the high efficiency both at high intensity of emission (AM1,5, 1000 W/m²), and at low and diffused illumination, also inside a room (with intensity within 10-100 W/m²).
