Leveraging decades of crystalline silicon material and solar cell/module market experience, AstroWatt has developed two key technologies that lower c-Si cell manufacturing cost per watt by 50% over other c-Si high-efficiency cell manufacturer's roadmaps and 30% below leading thin film technology roadmap targets.

Semiconductor-on-Metal (SOM?)

AstroWatt's SOM? substrate technology creates an ultra-thin silicon metallic substrate that is strong and flexible enough to be routinely handled in volume manufacturing with existing process and automation equipment. Starting with a conventional monocrystalline silicon wafer, the proprietary SOM? technology produces a substrate with the precise silicon thickness required for optimum efficiency. Dramatic savings in silicon consumption translates into the lowest production costs in the market for high-efficiency c-Si cells. With the elimination of handling and wafer breakage concerns of extremely thin silicon substrates, AstroWatt extends c-Si cell technology for use in both rigid and flexible c-Si modules.
