Researchers in Germany claim to have achieved new peak efficiency for large-area easy-to-fabricate silicon solar cells. A team at the Fraunhofer Institute for Solar Energy Systems (ISE) says it has demonstrated 19.3% efficiency for a particular kind of silicon solar cell.
Researchers say that using more advanced cell structures, as compared to current industry standards, they could demonstrate that efficiencies of 20% are “realistic in the near future”.
More than 80% of the solar cells manufactured today are based on crystalline silicon. Currently, silicon solar cells convert an average of 14-19% of incidental solar energy into electricity. According to Fraunhofer ISE, researchers are already looking at the 20% efficiency mark, which could help reduce solar PV costs.
