Problems solved by technology

However, due to the light-induced attenuation effect (long-term strong light irradiation causes defects inside the battery and reduces its photoelectric conversion performance), its popularization and application has been severely limited.
A large number of experimental studies have proved that for amorphous silicon cells, the light-induced attenuation effect will be significantly weakened at higher temperatures

Abstract

The invention relates to a novel solar refrigerator comprising a refrigerator body, a solar photovoltaic power supply device, a direct-current inverter compressor, a first condenser, a capillary tube, a first evaporator, an adsorption bed, a second condenser, a control valve, a liquid storage tank and a second evaporator, wherein the solar photovoltaic power supply device comprises a photovoltaic cell and a controller; the photovoltaic cell is covered with a spectrum selective composite layer formed by combining a selective reflecting film and a selective emitting film; the photovoltaic cell and the adsorption bed form a combined adsorption bed. The novel solar refrigerator has the following advantages that photovoltaic-thermal comprehensive utilization is achieved by means of integration of a solar flat-plate adsorption refrigeration system and a solar photovoltaic direct-current refrigeration system, and the refrigeration efficiency of the adsorption refrigeration system is further improved by means of the radiation refrigeration technology; in addition, high photovoltaic power generation can be achieved by using a cheap amorphous silicon photovoltaic cell, and the overall efficiency of the solar refrigerator is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, in particular to a solar refrigerator, in particular to the combination of solar adsorption refrigeration, solar photovoltaic DC refrigeration and radiation refrigeration technologies. Background technique [0002] The use of traditional refrigerators consumes a lot of conventional energy and indirectly pollutes the environment. From the perspective of my country's energy supply and environmental protection needs, the development of refrigerators using clean energy will be the general trend, and solar refrigerators are the most widely used. In addition, solar refrigerators play an important role in the storage of vaccines, medicines, and food in remote areas that are not yet connected to the power grid. Among many solar refrigerator technologies, solar photovoltaic refrigerators and solar adsorption refrigerators have broad application prospects, but there are still some defects ...
