At the 21st International Photovoltaic Science and Engineering Conference, held on November 28 December 2 in Fukuoka, Japan, Kaneka and imec present silver-free heterojunction silicon solar cells. The results were obtained by applying copper electroplating technology, which was developed by Kaneka based on imecs existing copper electroplating technology, A conversion efficiency of more than 21% was achieved in 6-inch silicon substrates with an electroplated copper contact grid on top of the transparent conductive oxide layer.
