JA Solar announced at the Intersolar event in Munich that it is teaming up with ECN to begin production of metal wrap-through (MWT) solar cell and module. The MWT technology is claimed to minimize shading loss at the front of the cell’s surface, thereby reducing efficiency losses within the cell. The collaboration builds on ECN’s 2009 world-record MWT module efficiency of 17.0% (aperture area) on mc-Si cells.
“We are very pleased to be working with ECN to develop the next generation MWT solar cell technology for high efficiency solar modules,” said Yong Liu, senior VP of Manufacturing and CTO of JA Solar. “The MWT technology can effectively increase photovoltaic module conversion efficiency with the benefit of higher power output and it allows further reduction of material costs, lowering the cost of solar electricity.”
