The new stage of solar cell efficiency improvement requires superior N-type mono-Si cells that promise lower oxygen content, less resistivity and longer minority carrier lifetime. A better engineered and proven crystal growth furnace is prerequisite to producing such quality mono-Si cells. In response to market development needs, Songci Electromechanica has obtained the solution for lowering the oxygen content of mono-Si cells, namely the low oxygen content type crystal growth furnace: SC-1600-LO₂.
