Ram, re: yield, Agreed that there's a difference between performing QC on the films prior to lamination (prior to cutting into cell-sized pieces), and performing QC on any sections of cells further down the assembly line. As I understand it, Lev's comments about yields fold both of these matters together, such that yield is the 'percentage of raw material that ends up in acceptable final cells.' Perhaps you want to know how to isolate the yield factors at each step. However, perhaps the identification of 'bad cells' at a certain later step is actually the identification of problems with the front-end film manufacture. (This was something I believe I attempted to address in the earlier referenced post.) In this case, it would not seem correct to report this 'yield' factor as being related to that later step. I'm satisfied with Lev's definition, esp if the yields end up being 90% or better, and they see ways to improve even more, and always catch any bad product before it goes out the door. Rich
