Abstract: The invention relates to a method for metallizing and connecting solar cell substrates and to a photovoltaic module made of several metallized solar cells that are electrically connected to one another. According to the invention, a solar cell substrate, in which second metal layers forming electrical metal contacts are optionally provided, is attached to a carrier substrate, on the surface of which at least one first metal layer is formed in a suitable pattern. By localized irradiation of the metal layer with laser radiation through the solar cell substrate or the carrier substrate, energy is introduced such that the metal layer is heated by absorbed laser radiation for an irreversible bonding to the adjacent surface of the solar cell substrate. By the laser bonding of the metal layer on the carrier substrate to the solar cell substrate, solar cells can be connected to form a photovoltaic module.

Abstract: Solar simulator that includes a pulsed radiation source for generating electromagnetic radiation, and at least one mirror element is arranged in a region of the radiation source. The at least one mirror element is structured and arranged to reflect components of radiation from the radiation source essentially in an intended irradiation direction. Further, the at least one mirror element, formed at least in part of metal, is positioned adjacent to the radiation source and is structured to receive at least a part of an ignition voltage of the pulsed radiation source. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
