BELGIUM: A 6-inch semi square heterojunction silicon solar cell has been developed by Kaneka and Imec. It has a power conversion efficiency of 22.68 per cent and has an electroplated copper contact grid at the top of the transparent conductive oxide layer. As per the companies, compared to the traditional silver screen printing technology, using electroplated copper to create the top electrode in heterojunction silicon solar cells is more cost effective and efficient.

"We are excited that we could support Kaneka in developing this breakthrough results. They prove the capabilities of copper metallisation for next-generation solar cells and strengthen our believe that in the future copper will play an important role in high efficiency and sustainable solar cell technology," said Jef Poortmans, Director, PV technologies, Imec.

According to Imec, “this development of large area Cu-plated heterojunction silicon solar cells is an important step towards a fab-compatible process on large area module integrated solar cells.”
