Techniques are disclosed for protecting a photovoltaic device from the environment. An electrical interconnection is also provided for increased mechanical and electrical protection of the photovoltaic and electrical interconnections between lens cell assemblies configured in an array using an enclosed busway structure. Also provided is a method of leading the electrical contacts from the photovoltaic material within the lens cell assembly such that there is a positive seal provided by the lens encapsulating material. One such embodiment comprises a passage within the lens itself, which serves as a conduit for electrical leads from the photovoltaic material. The internal passage for electrical leads enables the ability to completely wrap and seal the lens assembly with encapsulating film, which in combination with an enclosed busway operatively coupling an array of lens assemblies, allows for a highly manufacturable and secure seal over the photovoltaic system.
