...nt solar cell thickness from typically 200-250 µm down to 100 µm. Assuming a projected kerf loss of 120 µm for 2010, this will enable more than 50% additional wafers to be cut from each silicon ingot. Additionally, by using advanced solar cell device structures and module interconnection technology, we target to increase the average efficiency for these thin cells up to 19% for mono-crystalline a ...
