METHOD FOR ASSEMBLING SOLAR MODULES A MONOLITHIC SOLAR MODULE FROM CELLS OF PHOTOELECTRIC CONVERTERS BY USING AN ADHESIVE LAYER Russian patent published in 2018 - IPC H01L31/18 

FIELD: electrical engineering.

SUBSTANCE: invention relates to photoelectric converters, in particular to the technology for assembling solar modules and switching cells of photoelectric converters. Present invention can be used for monolithic solar modules based on photoelectric converters, made of single-crystal silicon, polycrystalline silicon, photoelectric converters, manufactured by heterostructural technology. Method comprises preparing a carrier with an adhesive layer. First cell with a pre-laid output bus is laid. Conductive adhesive is applied to the output bus or to the corresponding side of the cell or the first cell is laid in such a way that it protrudes beyond the carrier to allow subsequent switching. Conductive adhesive is applied to the following cells, by analogy with the first cell, wherein the frontal contact pad contacts the rear contact pad of the previous cell. Adhesive is applied to the rear contact pad of the last cell, and a second output bus is installed. Remaining strings are assembled by analogy. Received strings are commuted and encapsulated in modules. Rear cell is laid so as to provide the possibility of subsequent commutation. Front or rear glass or external polymeric carriers are used as a carrier. Laminate is used as an adhesive layer. Hotmelt adhesives, photopolymer adhesives, epoxy resins, TPO, EVA, silicones are used as an adhesive base.

EFFECT: use of the claimed invention provides increased reliability and strength of assembling monolithic strings, improved reliability of half-assembly, reduced likelihood of damage to strings of photoelectric converters during assembly, as well as increased yield of suitable modules for monolithic assembly technology by reducing the rejection during assembly of strings of photoelectric converters.
