Description:
Zusammenfassung: This thesis goes into the matter of applying the inkjet printing technology in the field of wafer-based crystalline silicon photovoltaics.The relevant inkjet and solar cell working principles are introduced. Based on a literature review the inkjet technology is classified into three different main concepts and respective sub-concepts. This classification does not only apply to the fabrication of solar cells. It is also applicable for other printing technologies in the whole field of printed electronics and functional printing.For each of the main structuring concepts, masking, additive structuring and subtractive structuring, a process is developed, evaluated and characterized.In the case of masking, the undercut phenomenon is addressed. Structures on dielectric layers that are masked with a hotmelt etch resist ink often show an increase in feature size after immersion in a wet chemical etching bath. To approach this issue, first the printing process is investigated
