The n-type cell was built with phosphorus-doped LPCVD poly-Si passivating contacts and achieved a remarkable open-circuit voltage of 691.7 mV. According to its creators, with some adjustments the cell may be suitable for commercial production.An international research group has fabricated a large-area bifacial TOPCon solar cell with passivating contacts based on in situ p-doped polycrystalline silicon (poly-Si) films, using low-pressure chemical vapor deposition (LPCVD). The scientists adopted an industrial approach for LPCVD and used a homogeneous boron-diffused front emitter and screen-printed ...Den vollständigen Artikel lesen ...
