NOVELTY - The method for connecting thin metal layers on polymer carrier (7) that is a part of thin film photovoltaic cell, comprises introducing an opening (8) in carrier foil (1) of the thin metal layers under use of laser radiation with pulse length of less than 1 mu s, where the thin layer is exposed in which a deterioration of the metal layer is prevented through laser irradiation parameters. The metal layers are positioned to each other in the area of the opening in the carrier foil. The metals pressed to each other are connected through laser radiation with the pulse length of greater than 1 mu s.    USE - Method for connecting thin metal layers on polymer carrier for the production of thin film photovoltaic cell.    ADVANTAGE - The method ensures reliable connection of thin metal layers on polymer carrier with high strength, low density and high surface quality thus ensuring the production of thin film photovoltaic cell with good flexibility and high performance.    DETAILED DESCRIPTION - The method for connecting thin metal layers on polymer carrier (7) that is a part of thin film photovoltaic cell, comprises introducing an opening (8) in carrier foil (1) of the thin metal layers under use of laser radiation with a pulse length of less than 1 mu s, where the thin layer is exposed in which a deterioration of the metal layer is prevented through laser irradiation parameters. The metal layers are positioned to each other in the area of the opening in the carrier foil. The metals pressed to each other are connected through laser radiation with the pulse length of greater than 1 mu s. The metal layer subjected on the carrier foil consists of copper. The thin metal layers or foils of different materials with strong different melting points are connected to each other by laser radiation, which is used from same source with different energy or temporal control of the applied laser energy. A neodymium-doped yttrium aluminum garnet laser with a wavelength of 106 mu m is used for the connection of the metal foils. Laser riveting of a contact strip or a flexible electric connection and the thin film photovoltaic cell is repeated by a laser rivet (13). The removal of the upper layer is carried out through laser processing, mechanical scratching or masking during thin film coating after positioning the rear contacts (2). The pulsed laser irradiation of the carrier material of the metal layer is carried out with a target up to remove the rear contact by a laser source with a wave length of 600-190 nm, a pulse duration of less than 1 mu s and a spot size of 5-500 mu m. The laser pulse for riveting has pulse duration of greater than 1 mu s and a wave length in infrared or visible spectral region. A hole is produced in the metal layer. The drilling of the hole into the metal layer is carried out by a pulsed laser with a pulse duration of less than 1 mu s. The opening is introduced in the metal layer before or after the rear side opening of the carrier foil of the metal layer or in the connection with the rivet. The laser radiation is divided into partial beams for simultaneous laser processing. The temporal progress or momentary power of the laser pulse is adjusted through mechanical, electro optical or optical means. INDEPENDENT CLAIMS are included for:    (1) contact strip for micro riveting with a flexible thin film photovoltaic cell;    (2) thin film photovoltaic cell with contact strip; and    (3) a method for the production of thin film photovoltaic cell.
