Photovoltaic devices are provided that include a thin film stack (of a plurality of photovoltaic cells connected in series to each other) on a transparent substrate, a first busbar electrically connected to the first terminal cell, and a second busbar electrically connected to the second terminal cell. An encapsulation substrate is on the plurality of thin film layers and defines a first connection aperture positioned over the first busbar and a second connection aperture positioned over the second bus bar. A first electrical connector is positioned on the encapsulation substrate and is electrically connected to the first busbar through the first connection aperture, and a second electrical connector is positioned on the encapsulation substrate and is electrically connected to the second busbar through the second connection aperture. Solar arrays and kits are also provided that include such photovoltaic devices and a connection cable.
