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.

Application specific solar cell and method for manufacture using thin film photovoltaic materials

A multi-terminal photovoltaic module includes an upper photovoltaic device which has a first upper electrode, an overlying upper absorber layer, an overlying upper window layer, and a second upper electrode. The upper absorber layer has an upper band gap in a first band gap range. The module also includes a lower photovoltaic device which has a first lower electrode, an overlying lower absorber layer, an overlying lower window layer, and a second lower electrode. The lower absorber layer has a lower band gap in a second band gap range. The module also includes a bonding material coupling the second upper electrode and the first lower electrode. Moreover, the module includes a first upper terminal coupling the first upper electrode and a second upper terminal coupling the second upper electrode. The module further includes a first lower terminal coupling the first lower electrode and a second lower terminal coupling the second lower electrode. In an embodiment, the module provides a first open circuit voltage provided between the first upper electrode and the second upper electrode and a second open circuit voltage provided between the first lower electrode and the second lower electrode. In an embodiment, the first open circuit voltage is different from the second open circuit voltage.
