THIN-FILM PHOTOVOLTAIC MODULE HAVING PROFILED SUBSTRATE Russian patent published in 2014 - IPC H01L31/48 

FIELD: physics.

SUBSTANCE: invention relates to solar power engineering. The thin-film photovoltaic module has a main substrate; a thin-film photovoltaic device placed in contact with the main substrate, wherein said photovoltaic device has a current-conducting bus which protrudes from the surface of said device; a polymer layer placed in contact with said photovoltaic device; a protective substrate placed in contact with said polymer layer; wherein said protective substrate is profiled to provide an cut opposite said current-conducting bus; and said polymer layer is situated between said photovoltaic device and said protective substrate, wherein said current-conducting bus protrudes 0.0254-0.508 mm from said surface of said device, and said cut has a depth equal to the protrusion of said current-conducting bus plus or minus 0-20%. The invention also discloses a method of making thin-film photovoltaic modules and another thin-film photovoltaic module made using said method comprising defined steps.

EFFECT: invention enables to design photovoltaic modules that are easy to manufacture and are stable.
