Abstract: Disclosed are apparatuses and methods for cutting thin film solar cells. The apparatus may include circular knife cutter rollers, each having a knife edge and coupled with a cutter arbor, support rollers, each coupled to a support arbor and having first and second outer surfaces and a circumferential gap between the first and second outer surfaces partially defined by a first side, a second side facing and offset from the first side, a first rounded edge where the first side intersects with the first outer surface, and a second sharp edge where the second side intersects with the second outer surface. The cutter arbor and support arbor are offset, and the knife cutter rollers and support rollers are axially spaced, such that one knife edge is positioned in the gap of each support roller and the web may be fed between the cutter arbor and the support arbor.
