1. A transparent photovoltaic glass pane, comprising:
a transparent glass panel;
one or more photovoltaic cells arranged on or in the transparent glass panel, each of the one or more photovoltaic cells having a light receiving surface to be exposed to light from a light source and being comprised of a semiconducting material having a spectral response to the light; and
a spectral conversion layer arranged between the light receiving surface and the light source and configured to convert photons from the light source of a first energy into photons of a second energy,
wherein the spectral response to the photons of the second energy is higher than the spectral response to the photons of the first energy, and
wherein the spectral conversion layer is a luminescent nano-coating printed on top of a surface of the transparent glass panel that faces the light source, said coating being printed by inkjet printing of an ink on top of said surface of the transparent glass panel, wherein the ink comprises a europium salt and a diketone compound in an inorganic polymer matrix of a silane derivative, wherein the inorganic polymer matrix comprises (aminopropyl)triethoxysilane and 3-(triethoxysilyl)propyl isocyanate hosting a europium-thenoyl trifluoroacetone complex.
