The company also uses a back-contact design — wherein all busbars and electrical connections are moved to the back of the solar cells — along with a flexible, conductive backsheet to more effectively spread the heat produced by a module. This lowers the nominal operating cell temperature of Silfab modules, providing a higher module efficiency.
UV rays can cause semiconductor materials within the solar cells to degrade, diminishing their performance and efficiency. The backsheet acts as a shield, protecting the cells from UV radiation. It’s important to note that over time, all backsheets will undergo a color change due to UV exposure.
When deploying solar backsheets, it is important to take into account potential issues such as delamination, bubbling, cracking, and yellowing, which can all indicate early signs of backsheet failure. When selecting backsheets, the cost is a crucial consideration. The solar backsheet is crucial in safeguarding the solar panel.
Water and dust particles can lead to corrosion and pitting, posing a threat to photovoltaic cells. The backsheet’s role is to shield against moisture-related damage, including corrosion of electrical connections, insulation degradation, and the risk of short circuits.
In most cases, normal backsheets are sufficient to meet the requirements of PERC (Passivated Emitter Rear Cell) solar panels. However, when it comes to N-type or N-type TOPCon (Tunnel Oxide Passivated Contact) solar panels, a more specialized approach is necessary.
A PV backsheet is a special layer that covers the back of a solar panel. Its primary role is to protect the solar cells and internal components, enhancing the panel’s performance and extending its lifespan. Typically, backsheets are made from multiple layers of composite materials, including polymers, fluoropolymers, and polyester.
Cells are encapsulated before being laminated with glass and the backsheet. So, in a typical solar module, you have the glass on top, an EVA sheet after that, followed by the cells, one more layer of EVA sheet below the cell, and finally the backsheet. Solar panels have typically two layers of EVA-based encapsulants in a solar module.

These lines are actually the front contacts that collect the electricity generated by the panel. Now, imagine a solar cell without these lines on the front. This is what we call a Back Contact (BC) solar cell. In BC solar cells, all the electrical contacts are moved to the back of the cell, allowing the front to capture more sunlight. This ...

They both use the same energy source – sunlight – but change this into different energy forms: heat energy in the case of solar thermal panels, and electrical energy in the case of photovoltaic panels.
