By Kelly Pickerel REC, a leading fully integrated European brand of solar panels, announces that the company has developed a formula and process to mass produce multicrystalline solar cells with efficiencies above 20%.
This achievement is attributed to improvements made at all steps – from silicon to cell production. A batch of cells processed in the production line delivered an average cell efficiency of 20.21%, with the best cell at 20.47% measured by an in-house tester with an external calibration cell.
REC is the first known manufacturer to successfully achieve such high cell efficiency on a multicrystalline platform for industrial-scale production. Beginning in November 2016,
