Ultrashort‐pulse Laser Structuring of Thin‐film Solar Modules
Abstract: With support from the German "Innovationsallianz Photovoltaik", the joint research project T4nPV demonstrated ultrashort‐pulse all‐laser scribed CIGS solar modules with a 5.9 % (relative) higher electrical conversion efficiency compared to conventional, mechanically scribed reference modules. This remarkable efficiency gain was achieved by a reduction of the interconnection width down to approximately 100 μm, made possible by high performance optics, sensor technology, control and actuation components, which were designed and built up in the course of the project. Further, exceptionally high output power levels up to 1400 W in an ultrashort‐pulse thin‐disk high power amplifier were achieved.
