1. A photovoltaic module comprising:
a front surface comprised of a transparent front support layer,
a back surface comprised of a back protective layer,
at least an encapsulating layer between the transparent front support layer and at least one solar cell,
the at least one solar cell comprising a front side and a back side,
the back side comprising at least one positive electrical contact and at least one negative electrical contact,
at least a second encapsulating layer between the at least one solar cell and a conductive material and with local openings to be occupied by an electrical connection between at least one positive electrical contact or the at least one negative electrical contact and the conductive material,
at least one reflective layer disposed below the at least one solar cell and at least partially below the space adjacent to the at least one solar cell, the at least one reflective layer comprising a surface for redirecting light to the at least one solar cell,
wherein at least a portion of the at least one reflective layer is overlapping with and facing the backside of the at least one solar cell,
wherein the at least one reflective layer is coupled with at least one polymeric layer to provide insulation between the at least one solar cell and the electrical connection.
