CAB-DW™ for 5 µm trace-width deposition of solar cell metallization top-contacts

This paper reviews methods for creating solar cell grid contacts and explores how cell efficiency can be increased using CAB-DW^TM. Specifically, the efficiency of p-i-n structure solar cells built in-house with 90 μm sputtered lines and 5 μm CAB-DW^TM lines were compared. Preliminary results of the comparison show a marked improvement in solar cell efficiency using CAB-DW^TM. In addition, a theoretical and experimental analysis of the dynamics of particle impaction on a substrate (i.e. whether particles stick or bounce) is presented including how this analysis may lead to further improvement of CAB-DW^TM.
