LASER RADIATION POWER CONVERTER Russian patent published in 2018 - IPC H01L31/304 H01L31/693 

FIELD: electricity.

SUBSTANCE: invention relates to devices for converting electromagnetic energy into electrical energy. Laser power converter (LPC) device for receiving incident electromagnetic radiation at a wavelength of about 1550 nm, the device comprising a substrate, comprising InP; and an active region comprising an n-doped layer and a p-doped layer, said n-doped and p-doped layers are formed from In_yGa_1-yAs_xP_1-x, matched to the parameters of the lattice with the substrate and configured to absorb photons of electromagnetic radiation with a corresponding wavelength of about 1550 nm, where x=0.948, 0.957, 0.965, 0.968, 0.972 or 0.976, y=0.557, 0.553, 0.549, 0.547, 0.545 or 0.544 respectively.

EFFECT: LPC device according to the invention can have an increased efficiency for converting radiation at a wavelength of 1550 nm into electrical energy in comparison with existing LPC devices.
