Zusammenfassung:	The present invention relates to a method for creating electrical contacts in optoelectronic and electronic devices, including high and low concentration solar cells, thin films, organic light emitting diodes (OLED) and in general any device requiring the extraction or injection of a current by means of electrical contacts. The method comprises the following stages: (a) depositing the contact material on the final substrate through the laser induced forward transfer (LIFT) of said material from a donor substrate to the final substrate, preferably using a pulsed laser and (b) sintering the contact material using a laser source, preferably a continuous laser. The contacts thus created present excellent conductivity and adherence properties, as well as high height (thickness) to width ratios.
