Abstract: A photovoltaic module is specified, comprising: a cylindrical light-transmissive tube enclosing an interior and having a main extension direction and a curved inner surface facing the interior, and a mechanically flexible photovoltaic component comprising a solar cell arrangement applied on a carrier film, wherein the photovoltaic component is arranged in the interior, the solar cell arrangement has a curvature, wherein the curvature follows the curved course of the inner surface of the tube at least in places and the solar cell arrangement at least partly covers the inner surface, wherein the covered inner surface forms a light passage surface of the photovoltaic module.

Abstract: Techniques for bonding a luminescent material to a thermally conductive substrate using a low temperature glass to provide a wavelength converter system are provided. A dichroic coating is deposited on a thermally conductive substrate. The dichroic coating includes alternating layers of a first material having a first refractive index and a second material having a second refractive index which is greater than the first refractive index. A buffer layer is deposited on the dichroic coating. A wavelength converter is bonded to the buffer layer by a layer of low temperature glass. In some embodiments, the wavelength converter includes a phosphor for converting a primary light from an excitation source into a secondary light.
