In recent years, Suntech Power has successfully commercialised its Pluto technology with 0.5 GW annual production capacity, delivering up to 10% performance advantage over screen-printed cells. As part of the ongoing development of Pluto technology, the next generation of Pluto has demonstrated an average cell efficiency over 20% on a 155 cm2 commercial-grade p-type wafers using mass-manufacturing processes and equipment, with the highest single-cell efficiency independently confirmed at 20.3%. This is believed to be a record efficiency for this wafer type. Further optimization work suggests the potential for further efficiency increase to approaching 23%.
