Cost-effective solar cells: Yangzhou University in China reduces silver use with aluminium paste

China's Yangzhou University researchers have developed a solar cell using tunnel oxide passivated contact (TOPCon) technology. This innovation significantly cuts costs by replacing the traditionally expensive silver paste with a screen-printed aluminium (Al) paste.

A spokesperson from the research team mentioned that they are still refining the innovation. However, they are currently undertaking tests with JA Solar, a leading Chinese solar module manufacturer, and Ruxing Technology Development Co. Ltd., a specialist in paste manufacturing, to test and enhance the technology.
