SolarCity and Panasonic claim setting world records for solar module efficiency

SolarCity’s panel was measured with 22.04 percent module-level efficiency by the Renewable Energy Test Center. The silicon-based bifacial PV cell combines n-type substrates, copper electrodes, thin-film passivation layers, and a tunneling oxide layer that yields high conversion efficiencies.
 A week later, Panasonic claimed the crown at 22.5 percent module efficiency and, according to PV Magazine, it was verified by Japan’s National Institute of Advanced Industrial Science and Technology.  Read more at
