Abstract:
1. A solar cell processing system comprising: one or more processors; and memory communicatively coupled with an readable by the one or more processors and having stored thereon processor-readable instructions, which when executed by the one or more processors cause the one or more processors to: process design information for an application specific solar cell, the design information being stored in a database accessible to the one or more processors; determine at least a cell size and a cell shape based on the processed design information; form a layered structure including one or more films of photovoltaic materials overlying the front surface region of a transparent substrate having a thickness, 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 being configured to provide one or more unit cells having the cell size and the cell shape; align a laser beam from the back surface region through the thickness of the transparent substrate to illuminate a first region within the one or more grid-line regions, subject a first portion of the layered structure overlying the first region to absorbed energy from the laser beam to separate the first portion of the layered structure from the first region, scan the laser beam from the first region to a second region along the one or more grid-line regions to cause formation of one or more unit cells having the cell size and cell shape; and transfer the one or more unit cells having the cell size and the cell shape.
