| Popis: | 35th European Photovoltaic Solar Energy Conference and Exhibition; 398-400 Hanwha Q CELLS has developed high-efficiency PERC silicon solar cells with a selective emitter, achieving an efficiency of 22.7% for a 6-busbar cell, with open-circuit voltage above 684 mV. The selective-emitter cells are fabricated using industrially-proven processes, including conventional screen-printing, on B-doped, p-Cz silicon wafers. This advance builds on our Q.ANTUM technology, which combines leading efficiencies with a lean fabrication sequence and proven stability against light- (and elevated-temperature) induced degradation. Q CELLS currently produces an annualized 3 GW of Q.ANTUM cells on p-Cz wafers. In mass production, the efficiency of our 6-busbar cells now averages 22.15%. This enables high power ratings up to 395 W, for modules with 144 half-cells. With the results presented here, we demonstrate the capability of our Q.ANTUM technology to continue increasing the cell efficiency to 23% and beyond, within the next couple of years. |
