Phase change material application in solar cooking for performance enhancement through storage of thermal energy: A future demand

Solar cookers offer a sustainable source of energy that may be utilized for cooking purposes. On the other hand, their major disadvantage is that they cannot be employed when there is a lack of sunshine by using thermal energy storage; it is possible to significantly overcome these limits. This paper analysis specifically the latest advancements in solar cooking, including its many components and the features of heat transmission involved. Over time, many geometric adjustments have enhanced the cooking efficiency, particularly in box-type solar cookers. The utilization of energy storage materials enhanced the efficiency during periods of little sunlight. Phase change materials have a greater impact when used as a storage medium, whereas sensible heat storage mediums are more cost-effective. Improved policy implications are necessary to get social and economic acceptance. Solar cooking technology requires a method for advancement to improve its efficiency, cost, and practicality. The objective of this paper is to give a comprehensive literature evaluation of the uses of phase change materials as thermal energy storage mediums to enhance the performance of solar cookers. This review paper takes a retrospective look at the recent years by reviewing the progress made in the area of phase change materials and their applications in various heat transfer devices such as solar cookers, heat exchange, and thermal storage systems. In addition, the many types of phase-change materials, nanofluids, and the challenges associated with enhancing the thermophysical properties of phase-change materials are discussed.
