A photovoltaic module includes a first transparent electrode layer characterized by a first sheet resistance, a second transparent electrode layer, and a photovoltaic material layer. The photovoltaicmaterial layer is located between the first transparent electrode layer and the second transparent electrode layer. The photovoltaic module also includes a first busbar having a second sheet resistance lower than the first sheet resistance. The first transparent electrode layer, the second transparent electrode layer, and the photovoltaic material layer have an aligned region that forms a centraltransparent area of the photovoltaic module. The central transparent area includes a plurality of sides. The first busbar is in contact with the first transparent electrode layer adjacent to at leasta portion of each of the plurality of sides of the central transparent area.
