Improved quality test method for solder ribbon interconnects on silicon solar cells

摘要

The field of photovoltaic (silicon solar cells) is an important driver for regenerative energy techniques. The technology and efforts regarding efficiency factor, quality, and costs are still under development. Currently, typical silicon solar cells are connected to so called strings by two or three solder coated copper ribbons. The common interconnection technology of silicon solar cells is soldering of solder coated copper-ribbons.
