Solar cooking presents a promising alternative to conventional cooking methods; however, its reliance on sunlight necessitates the integration of thermal energy storage for off-sun cooking. Phase Change Materials (PCMs) offer a viable solution to this problem. Despite their potential, many researchers have used PCMs in off-sun cooking tests without fully characterizing them to ensure they meet all storage requirements. For PCMs to be effectively utilized in commercial solar cookers, they must meet specific criteria. This review aims to address this gap by examining the PCMs employed in solar cooking, reviewing the thermal characterizations conducted on each, and highlighting any limitations reported in the literature. By comprehensively assessing the characteristics of these PCMs, this review serves as a valuable resource for evaluating their suitability and distinguishing between those that meet the necessary criteria and those that do not. Through this systematic analysis, researchers and practitioners can make informed decisions regarding the selection and utilization of PCMs in solar cooking applications.
