Researchers develop antimony-doped n-type silicon ingots to enhance solar module mechanical strength

An international team is proposing to use antimony-doped Czochralski-grown silicon as an alternative to n-type silicon for photovoltaic applications. Their analysis showed that 140 µm as-cut planar antimony-doped wafers exhibit slightly higher mechanical strength compared to common wafers doped with phosphorous.A team led by the Australian National University has investigated antimony (Sb)-doped Czochralski-grown silicon as an alternative n-type substrate for solar PV applications in a study that included the characterization of axial resistivity distribution, donor properties, and mechanical ...
