Abstract

Systems and methods taught herein provide thin film semiconductor devices such as thin film photovoltaic devices having via holes that enable electrical connection with a bottom surface of a topside contact of the thin film semiconductor device via the back side of the device (e.g., during mounting of the device). In some embodiments, the via holes are electrically insulated.
