If I have Aluminum fins L shape and copper fins with 5 mm thickness , how I can paste it on the rear surface of the PV panel to cooling it by natural convection ?
There are epoxy resins specifically designed with metal particles which have high thermal conductivity. You might try some of these.
Dear Duaa,
Welcome,
Adding to Tony, you can connect fins to the back of the solar panel by using thermal conducting adhesive materials. There are many vendors for such materials one of them Henkel, is given in the attached link:https://www.woronko-glue.com/sg_obrazki_/00002478_normg_001.pdf
Best wishes
From time of manufacturing of the solar panel the fins can be fabricated as part of the back of the collector, if needed, or you can use the epoxy resins specifically designed for metal.
There is one point to remember however. Fins rely on the ambient air to cool them and will work very well in mountainous areas where the sun is intense and the air cold. I don't think they are going to work at all well in low lying desert countries with high air temperatures. But by all means try them and see how effective they are in practice. You may gain more by ensuring your panels have, either built in or by covering them, good infra red reflecting glass. It's much easier to fit than fins!
Thank you all for all answers and information Tony Maine & Mahmoud H Onsa & Abdelhalim abdelnaby Zekry ,

Dear Zhi Peng Gordon LING ,
cooling PV by fins (natural convection) is less effictive.
the cooling will be more effictive if we use (forced convection) by fan or we can use optimize cooling system (fins natural convection with water cooling together).
best regard
Hello,
you can use silicone glue , its conductivity and adhesivity is so high, but as other friends said you can use other traditional ways to cool your PV Cells.
