APPARATUS AND METHOD OF CONVERTING ULTRAVIOLET RADIATION INTO ELECTRICAL ENERGY Russian patent published in 2020 - IPC H01L31/08 

FIELD: solar engineering.

SUBSTANCE: invention relates to solar engineering, in particular to a device and a method of converting ultraviolet radiation into electrical energy. Device for converting ultraviolet radiation comprises an optical filter and a photoelectric converter, between the optical filter and the photoelectric converter there is a scintillator and a luminophore for converting ultraviolet radiation to the red spectrum, for example in the form of a plate of yttrium-aluminum garnet with an admixture of europium ions Y₃Al₅O₁₂:Eu²⁺ or cerium ions Y₃Al₅O₁₂:Ce³⁺, and photoelectric converter has maximum spectral sensitivity in red spectral region of 620–780 nm. Also disclosed is a method of converting ultraviolet radiation energy.

EFFECT: disclosed inventions provide higher efficiency of converting ultraviolet radiation into electrical energy in range of 200–380 nm, wherein spectral sensitivity of the device in the ultraviolet range will increase to 0,6–0,8 relative units, and conversion efficiency of ultraviolet radiation energy is increased by 2-3 times.
