TL;DR: In this article, an absorption refrigerator driven by solar cells was tested by the alternation of solar irradiance 550 to 700 W/m2 as solar energy and 500ml ambient temperature water as cooling load, and the coefficient of performance (COP) of NH3-H2O absorption refrigeration system is about 0.25.
Abstract: This experiment is to study an absorption refrigerator driven by solar cells. Hand-held or carried in vehicle can be powered by solar energy in places without power. In the evenings or rainy days, it is powered by storage battery, and it can be directly powered by alternating current (AC) power supply if available, and the storage battery can be charged full as a backup supply. The proposed system was tested by the alternation of solar irradiance 550 to 700 W/m2 as solar energy and 500ml ambient temperature water as cooling load. After 160 minutes, the proposal refrigerator can maintain the temperature at 5–8°C, and the coefficient of performance (COP) of NH3-H2O absorption refrigeration system is about 0.25. Therefore, this system can be expected to be used in remote areas for refrigeration of food and beverages in outdoor activities in remote and desert areas or long-distance road transportation of food or low temperature refrigeration of vaccine to avoid the deterioration of the food or the vaccines.

TL;DR: In this paper, a thermal management system based on phase change materials (PCMs) is discussed. But, the performance of the PCM-based thermal management systems for each kind of electronic components, Li-ion batteries and photovoltaic (PV) cells is not discussed.
Abstract: Improper operating temperature will degrade the performances of electronic components, Li-ion batteries and photovoltaic (PV) cells, which calls for a good thermal management system. In this paper, specific attention is paid to the thermal management systems based on the phase change materials (PCMs). Performances of the PCM-based thermal management systems for each kind of these three devices along with the type of PCM used, thermal properties of that kind of PCM, like phase change temperature, enthalpy of phase change and thermal conductivity are discussed. Discussion in detail on techniques to improve the thermal conductivity of PCMs is made because of its crucial influence. Advanced-structure heatsinks with multi-layer PCMs and hybrid passive heatsinks combined with active cooling are also introduced. The PCM-based thermal management system is powerful in ensuring electronic devices, Li-ion batteries and photovoltaic cells working safely and efficiently.
