Photovoltaic thermal management technology based on phase change materials (PCM) has also been studied by many experts. This paper first introduces how PCM reduces the operating temperature and working principle of photovoltaic panels, and summarizes PCMs for various applications and photovoltaic systems.
However, due to the advantages of phase change materials, PCM materials are currently a field worthy of study. PCM can be applied to related research on building energy conservation and photovoltaic system applications. Any project needs to consider the cost problem.
The remainder is converted into heat, affecting the performance of the SCs . In view of this, the researchers developed a photovoltaic/thermal (PV/T) system that enables continuous supply through active cooling technology to keep PV module temperatures low.
Experts proposed PCM-based concentrated photovoltaic thermal management system to effectively solve the above problems, PCM has a high latent heat value, high uniform temperature performance and excellent plasticity, PCM can not only reduce the temperature of concentrated photovoltaic panels, and can store the system exists in the residual heat.
And the uneven temperature distribution will affect the performance of PV system in two ways: (i) due to the loss of output power, the system has experience efficiency loss; (ii) temperature changes cause thermal fatigue to cause irreversible damage, and excessive local heating reduces the reliability of the system .
Coventry et al. analyzed the temperature change of a single PV system. The internal temperature of the cell showed that there was a temperature difference of up to 287.15 K between the middle and the edge of the cell. The uneven illumination strongly affects the temperature distribution on the SC.
