I'm working on cooling photovoltaic panels using phase-change materials. I wanted to see what kind of phase-change material is usually used to cool solar panels and increase their efficiency?

To the best of my knowledge, cooling PV panels with PCMs is not yet commercialized. There are many research works considering various PCMs, but till now I don't recall we have one PCM that has been adopted as the best and the most efficient type for cooling PV panels. The cost of the PCM to be used is till problematic ... many PCMs are candidates but the cost of such solution in cooling PV panels is still an obstacle. However, the availability of Paraffin wax at low cost in certain countries may give this type of PCM the possibility of being adopted in the future.
Generally speaking, the main criterion for the selection of a suitable phase change materia (PCM) for cooling photovoltaic (PV) panels is its phase transition temperature (melting point), which should be close to the normal PV operating temperature of 25 °C. In addition, other important parameters including high values of thermal conductivity, latent heat, and stability in the cycling heat process are taken into account in order to reach an appropriate decision.
Now , I am writ ting a matlab code to simulate the PV - PCM , and I already simulated it by fluent. there are several types of pcm could be used like paraff wax or hydride salt . If need more help contact me by this email [email protected]
Hi all
Interesting topic, well I´ve seen your suggestions and they address the question of Mohammad. The PCM melting temperature could be optimized within a specific range of temperature (optimum operational temperature of your PV module).
@Hasan A Al-Asadi, do you have any published study of this specific research?
Bests,
Mo.
@Mohammad Saffari
Thanks for your support
I recommend to follow the question below:

Paraffin wax, there are many options, or high temperature fatty acids such as myristic acid (~54 degC) and palmitic acid (62~degC)
CaCl2.6H2O maybe is an option. It is cheap, nontoxic, and most importantly, nonflammable. However, futher research is needed to solve its segregation issue during phase change.
Thank you so much dear Chunjian
Yes, I came to this before. But I could not find it in Iran.
Is there any information about CaCl2.2H2O for use in this regard?

Hi, Mohammad,
You may find useful phycial peformance about CaCl2.6H2O in the attached paper.

Thanks but please note I asked for "CaCl2.2H2O" not CaCl2.6H2O
