Technology
Semiconductor on Metal
Semiconductor-on-Metal (SOM®)
AstroWatt's Semiconductor-on-Metal technology creates an ultra-thin silicon metallic that is strong and flexible enough to be routinely handled in volume manufacturing with existing process and automation equipment.
Litho-less Local Back Contact
Litho-less Local Back Contact (LBC)
As silicon thickness decreases, performance of the thin crystalline cell is enhanced with the formation of local back contacts and a back reflector.
