Method for fixing a photovoltaic cell connector on a surface of a photovoltaic cell, photovoltaic cell connector forming die, device for fixing a photovoltaic cell connector on a surface of a photovoltaic cell

A method for patterning the surface of a solder-covered photovoltaic cell connector on the light-incidence side of a photovoltaic cell, the method comprising:

• heating at least a part of the solder-covered photovoltaic cell connector which is in contact with the surface of the photovoltaic cell;
• bonding the photovoltaic cell connector to contact areas of the photovoltaic cell;
• patterning at least a part of the surface of the heated part of the solder-covered photovoltaic cell connector during said bonding so that a predetermined surface pattern is formed;
• and
• cooling the photovoltaic cell connector by means of which the pattern is fixed on the solder-covered surface of the photovoltaic cell connector,
• wherein the pattern is a trench pattern,
• wherein the surface of the cell connector is patterned in such a manner that incident light is reflected from the surface of the photovoltaic cell connector especially in such a manner that this leads to a total reflection at the glass/air interface of a photovoltaic module.
