Patent ID: 7476278

Claim:
An apparatus, comprising: a first roll; a second roll; a first module between the first and second rolls, the first module being configured to form a first plurality of discrete electrodes supported by a substrate; a second module between the second roll and the first module, the second module being configured to apply a first sacrificial material so that the first sacrificial material is supported by the discrete electrodes; a third module configured to apply a second sacrificial material so that the second sacrificial material is supported by the substrate, the third module being between the second module and the second roll; a fourth module between the third module and the second roll, the fourth module being configured to form an organic semiconductive layer comprising an organic semiconductive material, the organic semiconductive layer being supported by the first plurality of discrete electrodes; a fifth module between the fourth module and the second roll, the fifth module being configured to remove the second sacrificial material to form the organic semiconductive layer into discrete portions of the organic semiconductive material; and a sixth module between the fifth module and the second roll, the fifth module being configured to apply a conductive material so that the conductive material supported by the discrete portions of the organic semiconductive material, thereby forming a plurality of photovoltaic cells, each photovoltaic cell including one of the plurality of discrete electrodes and one of the plurality of discrete portions of organic semiconductive material.
