HETEROELECTRIC PHOTO CELL Russian patent published in 2008 - IPC H01L31/04 

FIELD: physics.

SUBSTANCE: invention can be used in the production of solar photo cells. The hetero-electric photo cell, which converts into electrical energy the electromagnetic radiation falling on it contains layers of the semiconductor located on a metallic plate of p- and n-type with pn as the transition between them, introduced into the n-type semiconductor nano-particles of metal of the size less than the wavelength of the specified radiation at concentration specified for the nano-particles in the specified layer (1-5) 10^-2 of the volume fractions. In the specified layer of the semiconductor of n-type nano-particles are enclosed in a shell having the form similar to the form of the surface specified nano-particles, made from a polymer, for example, PVP (poly 2-vinylpyridine), with a thickness of the characteristic size specified nano-particles. The invention makes it possible to substantially increase efficiency.

EFFECT: improved efficiency in the solar photo cells.
