NOVELTY - The photovoltaic assembly comprises a monocrystalline silicon lamina, a receiver element, a low-resistance layer (22) disposed between the lamina and the receiver element, a contact layer disposed between the low-resistance layer and the lamina, a non-reactive conductive barrier layer (26) disposed between the low-resistance layer and the contact layer, and a photovoltaic cell comprising the lamina. The lamina has a thickness of 1-20 microns. An adhesion layer is disposed between the low-resistance layer and the receiver element, or in immediate contact with the receiver element.    USE - Used as a photovoltaic assembly.    ADVANTAGE - The photovoltaic assembly allows for good ohmic contact to the lamina and good adhesion to the lamina and the receiver element, exhibits low resistance, good reflectivity and good tolerance to high temperature, and can be easily and economically fabricated without wasting silicon through excessive kerf loss.    DETAILED DESCRIPTION - The photovoltaic assembly comprises a monocrystalline silicon lamina, a receiver element, a low-resistance layer (22) disposed between the lamina and the receiver element, a contact layer disposed between the low-resistance layer and the lamina, a non-reactive conductive barrier layer (26) disposed between the low-resistance layer and the contact layer, and a photovoltaic cell comprising the lamina. The lamina has a thickness of 1-20 microns. An adhesion layer is disposed between the low-resistance layer and the receiver element, or in immediate contact with the receiver element. The contact layer is in immediate contact with the barrier layer, and has a thickness of less than or equal to 300 Angstrom . The barrier layer is in immediate contact with the low-resistance layer. The reacted regions of the contact layer are in immediate contact with the lamina, and a dielectric material intervenes between the lamina and the unreacted regions of the contact layer. An INDEPENDENT CLAIM is included for a method to form a photovoltaic assembly.    DESCRIPTION OF DRAWING(S) - The figure shows a cross-sectional view of a photovoltaic cell.
