چکیده
کاربرد ذخیره انرژی نقشی حیاتی در استفاده از فناوری های انرژی خورشیدی ایفا می کند. انواع مختلفی از کاربردهای ذخیره انرژی در دنیای امروز موجود است. مواد تغییر فاز (PCM) برای سیستم های مختلف انرژی خورشیدی برای حفظ طولانی مدت انرژی گرمایی مناسب هستند، زیرا تابش خورشیدی پراکنده است. این بررسی ادبیات کاربرد PCM را در نیروگاه های حرارتی خورشیدی، نمک زدایی خورشیدی، اجاق گاز خورشیدی، بخاری هوای خورشیدی و آبگرمکن خورشیدی ارائه می دهد. اگرچه در دسترس بودن و هزینه PCM ها پیچیده و بالا است، PCM ها به دلیل بداهه سازی پارامترهای فنی قابل توجه در اکثر روش های انرژی خورشیدی استفاده می شوند. یافتههای دقیق این بررسی، راه را برای توصیهها و روشهای آینده برای محققین هموار کرد تا کار را برای پیشرفتهای بیشتر سیستم انجام دهند.

Abstract
The energy storage application plays a vital role in the utilization of the solar energy technologies. There are various types of the energy storage applications are available in the todays world. Phase change materials (PCMs) are suitable for various solar energy systems for prolonged heat energy retaining, as solar radiation is sporadic. This literature review presents the application of the PCM in solar thermal power plants, solar desalination, solar cooker, solar air heater, and solar water heater. Even though the availability and cost of PCMs are complex and high, the PCMs are used in most solar energy methods due to their signifcant technical parameters improvisation. This review’s detailed fndings paved the way for future recommendations and methods for the investigators to carry work for further system developments.
Introduction
The energy demand around the world is escalating quickly due to enhanced industrialization and population. Conventional fuels and renewable energy resources are the predominant sources existing to meet the energy demand. However, CO2 emission, availability of conventional fuel, and global temperature rise are the major problems associated with fossil fuel use. Unconventional energy resources like geothermal, wind and solar energy are abundantly available and have no adverse environmental efects. But, unconventional sources of energy have certain limitations, like solar radiation non-existence during nighttime. A suitable technique is necessary for a solar energy system to store the energy during its availability efciently. So, solar energy system performance is signifcant in proper usage and energy storage technologies as solar energy is discontinuous. Heat energy retaining is possible through latent heat, sensible heat, and hybrid methods. In which latent heat storage has a predominant role in efectively storing the available energy during phase transformation. Among diferent latent heat storage methods, PCMs heat storage technique has a signifcant impact in efectively storing the energy at a specifc temperature during phase change. Many research works have been carried in PCMs energy storage methods around the globe to fulfll the requirements, particularly in storing the available solar energy during the daytime. PCMs investigation started in 1940 and gained popularity nowadays, particularly in solar radiation heat storage applications.
Conclusion
Phase change materials can be applied to various solar energy systems for prolonged heat energy storage, which is relatively sound as the solar energy is discontinuous and is inaccessible during the night period. The review article shows a detailed study on the classifcation of Phase change materials, performance, and applications. The review paper exposes the applications of PCM in solar thermal power plants, solar desalination, solar cooker, solar air heater and solar water heater. The main aim of these applications in PCM is to enhance the economically viable efciency of PCM in solar thermal energy utilization.
