Abstract

The invention discloses a novel photovoltaic photo-thermal integrated assembly comprising photovoltaic cells, a U-shaped heat exchange tube assembly, and vacuum glass tubes. Photovoltaic cells arranged at multiple rows are arranged at intervals. The U-shaped heat exchange tube assembly that is provided with a heat absorption medium inlet and a heat absorption medium outlet and is arranged below the photovoltaic cells contains a plurality of U-shaped heat exchange tubes that are connected in parallel and or in series. Multiple vacuum glass tubes are arranged below the photovoltaic cells and each glass tube is located between the gap between each two adjacent rows of photovoltaic cells; and the U-shaped heat exchange tube arranged below the gap between each two adjacent rows of photovoltaic cells is arranged in the vacuum glass tube. According to the novel photovoltaic photo-thermal integrated assembly, the solar radiation energy is absorbed by the photovoltaic cells and the vacuum glass tubes arranged in the gaps of the photovoltaic cells simultaneously, thereby improving the solar utilization rate.

Description

technical field [0001] The invention relates to the technical field of solar photothermal photovoltaic technology, in particular to a novel photovoltaic photothermal integrated component. Background technique [0002] As a renewable energy that has attracted much attention, solar energy has always been a research hotspot in its new application technology and form. In actual photovoltaic applications, it is found that the conversion efficiency of solar crystalline silicon cells is about 12% to 17% under standard conditions, that is, about 80% of the solar energy irradiated on the surface of the cell will be converted into heat energy. For silicon cells , every time the working temperature rises by 10°C, the photoelectric conversion efficiency drops by 6% to 8%. Therefore, it is necessary to take measures to cool down the photovoltaic panels and recycle excess heat at the same time. The solar photovoltaic photothermal integration technology combines photovoltaic modules and h...
