Abstract

The present highly competitive state of the PV industry is putting the pressure on both crystalline and thin film manufactures to deploy advanced architectures as a means to differentiate their products and protect market share. c-Si back side contact passivation, selective emitter opening and selective emitter doping are three efficiency improving processes that can utilize lasers that the industry is rapidly moving to adopt. Emitter Wrap Through (EWT) is another advanced architecture which will likely see adoption in the coming years for which lasers are a critical component of the process. Improved laser TCO patterning is of interest not only for CdTe solar cells but also for display and other micro electronics applications. Laser processing results for these various solar PV materials are presented both in terms of performance, materials science, and morphology as they relate to temporal characteristics of the laser pulse.
