本文讨论了相变材料光伏系统的热、电管理问题。本文综述了PV-PCM技术的研究现状，以及该技术面临的研究空白和挑战。综合文献综述阐述了该技术的不同方面，如系统开发，性能评估，PCM选择，传热增强，模拟和在实践中的应用。本文还详细讨论了将PCM纳入光伏系统所产生的成本。当前综述的主要发现是，通过使用PCM，光伏电池板的峰值温度可降低至20 °C，电转换效率可提高5%。在峰值时段，每平方米光伏板面积平均需要~ 2.6 kg的PCM来降低光伏板的一度温度。目前的综述认为，由于技术挑战、系统成本高以及合适的pcm的可用性，PV-PCM冷却系统尚未商业化。然而，PV-PCM系统仍处于研究阶段，具有很大的实际应用空间。针对当前面临的挑战，对今后的工作提出了建议。
Thermal and electrical management of the PV systems integrated with Phase Change Materials has been discussed in this article. The main aim of this review article is to provide the current status of PV-PCM technology along with the research gaps and challenges being faced by this technology. A comprehensive literature review elaborating different aspects of this technology, such as system development, performance evaluation, PCM selection, heat transfer enhancement, simulation, and application in practice is presented. Cost incurred due to inclusion of PCM into PV system is also discussed in detail in this article. Major findings of the current review are that PV panel peak temperature can be reduced up to 20 °C with an increase in electrical conversion efficiency up to 5% by using PCM. At an average, ~ 2.6 kg of PCM is needed per meter square of the PV panel area to reduce the one-degree temperature of the PV panel during peak hours. The current review concludes that PV-PCM cooling system is not yet commercialized because of technological challenges, high system cost, and availability of appropriate PCMs. However, PV–PCM systems are still in the research phase, with great scope for practical applications. Suggestions for the future work along with current challenges are also presented.
