Project Panda, a research partnership started in 2009 between Yingli Green Energy Holding, the Energy Research Center of the Netherlands (ECN) and Amtech Systems’ solar division Tempress Systems, revealed that its N-type Metal Wrap Through (N-MWT) PV cell and module technology had reached a cell efficiency of 19.7% and a module efficiency of 17.6%.
The companies maintain that the N-MWT PV cell technology could reduce up to 40% of the metal coverage, compared to standard crystalline cells, and lead to nearly a 1.5% relative cell efficiency gain. Furthermore, ECN noted that it had demonstrated that the PV modules based off N-MWT technology could be made with thin cells at a high yield. This possibility carries the potential to diminish wafer thickness and silicon consumption, which would in turn create a cost reduction.
