Photovoltaic devices are generally provided that can include, in one particular embodiment, a transparent substrate; a plurality of thin film layers defining a plurality of photovoltaic cells connected in series to each other on the transparent substrate; a first lead connected to one of the photovoltaic cells; and, an encapsulation substrate on the plurality of thin film layers. The encapsulation substrate can generally define a back surface and a connection aperture through which the first lead extends. A junction box can be positioned over the connection aperture and connected to the first lead. The junction box generally comprises a support member extending through the connection aperture to mechanically support the transparent substrate in an area opposite to the connection aperture. Methods and kits are also generally provided.
