Krause, S J

This patent describes a process for preparing a solar cell assembly. It comprises: furnishing a solar cell base having a substrate, an etch stop layer overlying the substrate, and a solar cell having a layer of p-type semiconductor and a layer of n-type semiconductor overlying the etch stop layer. The solar cell further having two electrical layer contacts, one to each of the semiconductor layers. The layer contacts each having an external contact surface exposed on a top side of the solar cell; placing a glass cover over the solar cell with a bottom surface of the glass cover in proximity with the top side of the solar cell, the glass cover having a pair of electrical cell contacts extending from the bottom surface of the glass cover to the top surface thereof. The portion of each of the electrical cell contacts at the bottom surface of the glass cover being disposed adjacent to one of the layer contacts at its external contact surface; joining each of the pair of electrical cell contacts to one of the pair of electrical layer contacts; and etching away at least a portion of the substrate to reduce the total thickness of the solar cell base.
