Patent ID: 7772484

Claim:
A module, comprising: a first photovoltaic cell including a substrate and first and second electrodes, the second electrode of the first photovoltaic cell being above the first electrode of the first photovoltaic cell, the second electrode of the first photovoltaic cell being between the substrate of the first photovoltaic cell and the first electrode of the first photovoltaic cell; a second photovoltaic cell including first and second electrodes, the second electrode of the second photovoltaic cell being above the first electrode of the second photovoltaic cell; and an interconnect disposed in the second electrode of the first photovoltaic cell and disposed in the first electrode of the second photovoltaic cell without being disposed in the first electrode of the first photovoltaic cell, wherein: a portion of the substrate of the first photovoltaic cell is between the second electrode of the first photovoltaic cell and the first electrode of the second photovoltaic cell; the portion of the substrate of the first photovoltaic cell that is between the second electrode of the first photovoltaic cell and the first electrode of the second photovoltaic cell comprises a material selected from the group consisting of glass, polymers and combinations thereof; the interconnect is disposed in the portion of the substrate of the first photovoltaic cell that is between the second electrode of the first photovoltaic cell and the first electrode of the second photovoltaic cell; the interconnect is electrically conductive; and the interconnect electrically connects the first electrode of the second photovoltaic cell and the second electrode of the first photovoltaic cell so that the first and second photovoltaic cells are electrically connected in series.
