At the 21st International Photovoltaic Science and Engineering Conference, held on November 28th - December 2nd 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 imec's 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.
Today, silver screen printing is the technology of choice for the realization of the top grid electrode in heterojunction silicon solar cells.
