text: By 2012 available efficiencies exceeded 20%, and the maximum efficiency of research photovoltaics was in excess of 40%.
text: Average efficiencies in production for the major players such as the ‘Silicon Module Super League’ (SMSL) members (Hanwha-Q cells, JA Solar, LONGi, Trina Solar, JinkoSolar and Canadian Solar) have between 21.5% and 22% conversion efficiencies, which are outstanding compared to standard Al-BSF technology, which had dominated the market for decades and where the best average efficiencies hardly exceeded 20%.
