Abstract
A method for manufacture of application specific solar cells includes providing and processing custom design information to determine at least a cell size and a cell shape. The method includes providing a transparent substrate having a back surface region, a front surface region, and one or more grid-line regions overlying the front side surface region. The one or more grid regions provide one or more unit cells having the cell size and the cell shape. The method further includes forming a layered structure including photovoltaic materials overlying the front surface region. Additionally, the method includes aligning a laser beam from the back surface region to illuminate a first region within the one or more grid-line regions, subjecting a first portion of the layered structure overlying the first region to the laser beam to separate the first portion of the layered structure from the first region, and scanning the laser beam along the one or more grid-line regions to cause formation of one or more unit cells having the cell size and cell shape. The method further includes transferring the one or more unit cells.
