Abstract: The overheating problem of the PV panels and its consequences (e.g. electrical performance degradation, thermal failure, and the short life spans) opened the gate to many studies that are aiming to solve this problem. The most recent studies have proposed replacing the conventional PV and PV/Thermal (PVT) systems with new systems that depend on optical filtration (OF) and nano-enhanced phase change materials (nanoPCM). This work provides a combined review, for the two approaches with a comprehensive numerical assessment for the feasibility of using OF and nanoPCM in different integration to the conventional single PV and hybrid PVT systems. The results declared that using OF, side by side, with the cooling fluid (CF) appeared as one of the best ways for PV cooling. It has allowed for a reduction of 42.1% and 6.3%, on the average PV temperature, compared to the conventional PV and PVT systems, respectively. To the moment, solar obstruction put the system with OF as more thermally, while less electrically, efficient compared to the PVT system. Apart from the OF, using nanoPCM, at low nanoparticle loadings, is not recommended as it can increase the average PV temperature by 81.2% at five suns solar concentrations. However, the enriched nanoPCM (high loadings) is considered an excellent way for thermal regulation to achieve a low-temperature gradient along with the PV panel. A more detailed explanation of the results is presented in the manuscript. This work is considered the first to cover such comparisons that result in an understanding of the pros and cons of the OF and nanoPCM and their expected value when integrated to different PV-based hybrid solar systems.
