摘要

On July 1st, 2006 the “Restriction of the Use of Certain Hazardous Substances (RoHS)” took effectwhich results amongst others in a lead ban from nearly all electric and electronic products. The classicalmicroelectronic packaging technologies made arrangements to meet these lead free demands by developing newsoldering materials and optimized soldering technologies. So far, photovoltaic modules are excepted from the RoHSrestriction. However, lead in the cell metallization as well as in the cell connections curtail the environmentallyfriendlyimage of photovoltaic and should result in R&D activities to eliminate lead. Due to the long-term experiencein lead free soldering, synergies between microelectronics and photovoltaic can initiate new developments for leadfree cell connections. This work presents the fundamental studies of the last two years especially for the adjustment ofsolder chemistry. Different ways to enhance the wettability of Si bulk solar cell metallization by alternativemetallization finishes, optimized flux media, lead free solder materials and solder processing will be discussed.Recommendations for the soldering of thin solar cells will be made.
