Abstract:
Embodiments of the invention provide a method of forming a composite solar cell structure that includes preparing a device substrate, wherein the device substrate includes a glass substrate, a transparent conductive layer deposited over the glass substrate, one or more silicon layers deposited over the transparent conductive layer, a back contact layer deposited over the one or more silicon layers, and one or more internal electrical connections disposed on the back contact layer. The method also includes forming a mating pattern on a bonding material to match a topography of an exposed surface of the device substrate, the exposed surface comprising the back contact layer and the one or more internal electrical connections. The method also includes positioning the bonding material over the exposed surface, disposing a back glass substrate over the bonding material to form a composite structure, and compressing the composite structure. Embodiments of the present invention also include methods of preparing a pre-patterned bonding material for a solar cell assembly.
