For c-Si solar cells the primary laser application today is edge isolation and this is well-established in industrial production of most types of wafer-based cells. Other laser processes are used in the production of advanced high-efficiency c-Si cell designs such as laser grooved buried contacts, emitter wrap-through or metal wrap-through inter-
Drying and Storage. Wafers in cassettes are commonly dried using a spin rinse dryer or a centrifuge prior to the next process. If wafers are not immediately processed, they need to be stored in a clean environment and inert environment, such within a dedicated nitrogen (N 2) storage cabinet, which has a constant nitrogen gas purge. – W. Kern, “The Evolution of
