No, material for layer 5 has already been decided. Aluminium backsheet shall be used there. A suitable material in between the PV module and the aluminum backsheet is required which conducts the heat from the PV module to the heat mat. This material should also be an electrical insulator for maximum efficiency of the PV/T systemberkeman said:Welcome to the PF.
Do you mean Layer 5 in the diagram from Wikipedia?

hexagonal boron nitride, Al2O3 and silicone rubbers. I am currently doing more research to find and eventually order some samples for my experimentanorlunda said:
I appreciate your feedback, Tom. The PV module to be used in my experiment is based on neutral gas i.e. no encapsulant (EVA). I am thinking to go ahead with fillers in a polymer matrix, just want something concrete to go ahead with. This forum has been really helpful, Cheers!Tom.G said:
The best material for a glass/glass PV/T (photovoltaic/thermal) system is a combination of low-iron tempered glass and monocrystalline silicon solar cells. This combination allows for high efficiency in converting sunlight to electricity, as well as durability and resistance to harsh weather conditions.
Low-iron tempered glass is preferred for a PV/T system because it has a high transmittance rate, allowing more sunlight to pass through and reach the solar cells. It also has a lower iron content, reducing the risk of discoloration and improving the overall efficiency of the system.
Yes, there are other materials that can be used for a glass/glass PV/T system, such as polycrystalline silicon solar cells and anti-reflective coated glass. However, these materials may not provide the same level of efficiency and durability as low-iron tempered glass and monocrystalline silicon solar cells.
The choice of material can greatly affect the performance of a PV/T system. The right combination of materials can result in higher efficiency, better durability, and longer lifespan of the system. On the other hand, using lower quality materials can lead to lower efficiency, shorter lifespan, and increased maintenance costs.
When choosing the best material for a glass/glass PV/T system, factors such as efficiency, durability, cost, and compatibility with other system components should be considered. It is important to also consider the specific climate and weather conditions of the installation site to ensure the chosen materials can withstand them.
