MWT plug metallization: improved performance and process stability of PUM and ASPIRE cells
conference paper
In this paper we present an alternative to our metal-wrap-through PUM߿ݠmetallization concept that simplifies the cell process and thereby reduces manufacturing costs. The simplified printing step allows complete filling of the holes with a specially designed conductive paste. With this plug߿ݠconcept of closed PUM holes we achieved a feasible, more stable process, performing better than the reference PUM process by showing an absolute increase of 0.2% in efficiency. In this form, the PUM process showed to be industrially feasible. The implementation of the plug metallization in the ASPIRe cell concept was successful as well. The first plug߿ݠASPIRe cells performed as well as expected from the PUM results, showing a maximum efficiency of 15.9%. Keywords: metal-wrap-through, bifacial, plug metallization
