Kerfless wafers substantially reduce the cost of Si solar cells

World-leading nanoelectronics research center imec and Crystal Solar, a pioneer in direct wafer growing technologies for the next generation of solar photovoltaic products, today announced that they have achieved a 22.5 percent cell efficiency (certified by FhG ISE CalLab) with nPERT silicon (Si) solar cells manufactured on 6-inch mono-crystalline epitaxially grown kerfless wafers. Marking an industry first, imec and Crystal Solar have demonstrated the highest efficiency to-date for homojunction solar cells on epitaxially grown silicon wafers, paving the way toward industrialization of this promising technology.
