Post-Separation Processing for Silicon Heterojunction Half Solar Cells With Passivated Edges

We investigate different postseparation process routes for silicon heterojunction (SHJ) half solar cells, separated by thermal laser separation. SHJ half cells with and without aluminum oxide (Al2O3) deposition as edge passivation layer undergo different annealing processes, including i) a hotplate; ii) an inline oven; and iii) an ultrafast light soaking process. SHJ half cel...
