Disclosed is a photovoltaic assembly capable of improving the efficiency of generating electrical energy through high effects of light collection and heat radiation. The photovoltaic assembly of the present invention includes: a light collecting unit for collecting solar light incidents from a Fresnel lens; a cell receiver for converting the solar light collected by the light collecting unit into an electrical signal; a heat sink which supports the light collecting unit and the cell receiver, and is fixed onto an inner surface of a housing; and a heat radiation block coupled to the heat sink at an outer surface of the housing with the housing interposed therebetween.
