PHOTOVOLTAIC MODULE WITH NANOSTRUCTURE PHOTOCELL Russian patent published in 2011 - IPC H01L31/52 B82B1/00 

FIELD: physics.

SUBSTANCE: photovoltaic module with a nanostructure photocell (1) has a primary optical concentrator (3) in form of a Fresnel lens whose optical axis (4) passes through the centre of the photoactive region (2) of the nanostructure photocell (1), made in form of a circle of diameter d and a secondary concentrator in line with the primary concentrator (6).The secondary concentrator (6) is placed at distance h₁ from the front surface of the Fresnel lens and consists of a front optical element (8) in form of part of a sphere of radius R, base diameter D and height h₂, an intermediate optical element (10) of thickness h₃ with parallel front and rear surfaces and a rear optical element (11) made in form of a cylinder of diameter d and height h₄, where values h₁, h₂, h₃, h₄, R and D satisfy certain relationships.

EFFECT: photovoltaic module is simple to design, has good photovoltaic characteristics, provides reliable and long-term operation.
