Reflective concentrating photovoltaic system based on phase change heat storage and radiation refrigeration

Abstract

The invention discloses a reflective concentrating photovoltaic system based on phase change heat storage and radiation refrigeration, and belongs to the technical field of new energy utilization. The problems that the output power of a photovoltaic module is low and the cooling effect of a battery is poor under the concentrating photovoltaic condition due to the fact that the existing concentrating photovoltaic and radiation refrigeration combined utilization effect is not ideal are solved. The system comprises a concentrating photovoltaic device, a phase change heat absorption assembly, a radiation refrigeration coating and a supporting frame, wherein the concentrating photovoltaic device comprises a ground reflector, a Fresnel condenser and a photovoltaic cell, the ground reflector, the Fresnel condenser and the phase change heat absorption assembly are respectively installed on the supporting frame, the phase change heat absorption assembly is arranged in parallel to the Fresnel condenser, the photovoltaic cell is attached to the side surface, which faces the Fresnel condenser, of the phase change heat absorption assembly in parallel, sunlight is reflected to the Fresnel condenser through the ground reflector, and the photovoltaic cell is covered with condensation light spots formed by the Fresnel condenser.

Description

technical field [0001] The invention relates to a reflective concentrating photovoltaic system based on phase change heat storage and radiation cooling, and belongs to the technical field of new energy utilization. Background technique [0002] In today's society, under the background of energy crisis and sustainable development requirements, the development and utilization of new energy has always been a research hotspot at home and abroad. Especially in my country, as a developing country with a large energy demand, the energy utilization structure dominated by fossil energy is relatively unreasonable. At present, there is an urgent need to convert new and old kinetic energy to adjust the energy structure. The development and application of new energy, especially solar energy, will enter the new era. There are many ways to utilize solar energy, among which photovoltaic power generation, which directly converts solar energy into electrical energy, is the most common and dir...
