Researchers at Chinese solar manufacturer Longi have investigated the physical mechanisms behind edge masking in high-efficiency solar cells, finding that the technique suppresses edge recombination by restricting lateral carrier transport. Edge masking is a laboratory measurement technique in which the perimeter of a solar cell is covered with an opaque material to prevent illumination of its edges, thereby reducing recombination losses and potentially increasing measured conversion efficiency. "Our starting point was a practical concern about how efficiencies are measured," Longi researcher ...Den vollständigen Artikel lesen ...
