Abstract

The invention relates to a solar thermophotovoltaic (STPV) system. The STPV system comprises a photovoltaic module, a photothermal module and a mounting frame, wherein the photovoltaic module is arranged at the upper part; a heat collection part of the photothermal module is arranged at the lower part; the photovoltaic module and the photothermal module are fixed together through the mounting frame; and the front side and the rear side of the photovoltaic module are packaged with transparent material. The STPV system has the advantages of high photoelectric conversion efficiency, high heat collection efficiency, high convenience in installation and the like, and can be applied to a building in the way of being laid on a flat roof, a slope roof, a balcony, a rain shed and the like.

Description

technical field [0001] The invention belongs to the fields of photovoltaic and photothermal, and relates to a system combining photovoltaic and photothermal. Background technique [0002] Photovoltaic-thermal integration applications have been developed for many years, mainly in the field of concentrating photovoltaic systems. Since concentrating photovoltaic systems generate a lot of heat, cooling is originally required, especially for high-power concentrating photovoltaic systems, which generally use water cooling. The concentrating photovoltaic system is used as the main part of heat collection, and the heat transfer is carried out by means of water circulation. The heat conversion efficiency is low, and it cannot be installed in combination with the building, and the current technology of the concentrating photovoltaic system is not yet mature. [0003] In recent years, some photovoltaic modules and vacuum tube heat collectors have been integrated together, and photovolt...
