NOVELTY - The panel (10) has two transparent sheets (12, 14) between which an evacuated cavity (16) is formed. An array of support pillars (18) extends between the transparent sheets. An array of photovoltaic cells (32) is adjacent or against one of the transparent sheets. A concentration unit concentrates solar radiation onto the photovoltaic cells, where the concentrating unit comprises a lenticular array to concentrate incident solar radiation onto the photovoltaic cells. A third transparent sheet (30) sandwiches the photovoltaic cells against the transparent sheet.    USE - Evacuated photovoltaic glazing panel for use in a building such as commercial building and domestic building.    ADVANTAGE - The evacuated cavity minimizes convective and conductive heat transfer between the transparent sheets so as to provide maximum thermal insulation that can be up to seven times higher than that of existing double glazing units while generating electricity through solar energy in order to reduce and supplement power requirements of the building, thus significantly reducing a carbon footprint of the building. The panel allows large amounts of the electricity to be generated by using only a fraction of a photovoltaic material used in existing photovoltaic glazing, so that an evacuated glazing portion of the panel is less bulky and lighter than existing double glazing units as a minimal amount of evacuated space is required in the cavity. The panel enables a set of lenses to be designed to produce seasonal effect with more light allowed into the building in winter months and less in summer months, so that the panel offers significant energy savings by reducing heating and cooling load of buildings and allowing effective daylight control, thus providing improved thermal comfort, very low heat loss, better sound insulation and reduction in peak energy demand, and hence reducing cost of photovoltaics as a building integrated system.    DETAILED DESCRIPTION - The transparent sheets are made of glass. The support pillars are made of stainless steel, ceramic and/or glass.
