A method for manufacture of unit cells for thin film photovoltaic materials includes providing an optically transparent substrate having a thickness, a back surface region, and a front surface region including one or more grid-line regions. The method further includes forming a layered structure including photovoltaic materials overlying a metal layer on the front surface region. Additionally, the method includes aligning a laser beam from the back surface region through the thickness of the optically transparent substrate to illuminate a first region within the one or more grid-line regions and subjecting a portion of the metal layer overlying the first region in the laser beam to separate a first portion of the layered structure from the first region. The method further includes scanning the laser beam along the one or more grid-line regions to cause formation of one or more unit cells of the layered structure and providing the one or more unit cells.
