Polycrystalline Silicon for solar energy applications includes p-type and n-type silicon.silicon Find Safety and Research information below. Silicon-based photovoltaic cells (PV Cells) for solar energy are fabricated from a positively charged or p-type silicon layer underneath a negatively charged or n-type silicon layer. These layers can be produced from casted polycrystalline material sold under the AE Solar Energy group.  Most silicon-based PV solar cells are produced from polycrystalline silicon with single crystal systems the next most common. Silicon Metal is also  available as single crystal, amorphous silicon, disc, granules, ingot, pellets, pieces, powder , rod, sputtering target, wire, and other forms and custom shapes. Ultra high purity and high purity forms also include submicron powder and nanoscale powder. Polycrystalline Silicon is generally immediately available in most volumes. Technical, research and safety (MSDS) information is available.
