FLEXIBLE PHOTOELECTRIC MODULE MANUFACTURING METHOD Russian patent published in 2019 - IPC H01L31/18 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, specifically to methods of making flexible photovoltaic modules for converting solar radiation energy into electricity, which can be used to power consumers and charge accumulators on board electric and hybrid vehicles of sea and air application. According to the method of producing a flexible photoelectric module, a first protective layer is formed from a flexible flat sheet of a transparent electrically insulating polymer, an adhesive is applied on its outer layer, subjected to heat treatment and covered with a protective film. Then, second protective layer is formed from flexible sheet of transparent electrically insulating polymer, water-repellent coating is applied on its outer layer in liquid phase and dried at temperature of 20–60 °C. Protective layers are fixed in process accessories, conductive wires coated with low-temperature solder are applied in parallel with crosswise buses perpendicular to them and lubricated with process adhesive. Central layer of flexible flat sheet of transparent electrically insulating polymer is placed on both protective layers with windows for photoelectric converters pre-punched opposite to conductive wires and between them – windows for transverse buses, such that transverse tires of said protective layer are located in corresponding openings. Single photoelectric transducers are arranged in corresponding openings and the obtained assembly is covered with the remaining protective layer so that transverse buses of this protective layer are located in corresponding windows. At the final stage, the assembly is placed in a laminator at temperature of 100–180 °C for 10–15 minutes.

EFFECT: invention simplifies production of a flexible photoelectric module.
