A conventional monocrystalline or polycrystalline solar cell is a layer slightly thicker than a human hair. It is not only such a thin structure, but it is solid and brittle, so it needs careful protection with materials such as metal and glass.
The name of flexible solar panels used in the solar industry is thin film panels. Although these flexible panels are 300 times thinner than a conventional solar panel, they can be flexed without losing their functions. On the other hand, it has lower efficiency compared to a conventional solar panel. Compared to solid solar panels with efficiencies of 16-25%, thin-film solar panels fall between 7-15% so more panels are needed for the same power plan.
Thin-film solar panels are not preferred much in rooftop solar energy systems, but they are mostly used in boats, boats, caravans, solar-powered electric vehicles, and mobile transportation vehicles that have a weight disadvantage.
One of the biggest advantages of flexible solar panels is that they can adapt to many solar projects. For example, in a house that does not have a strong roof, a thin-film solar panel can be preferred instead of a monocrystalline or polycrystalline solar panel weighing 30-40 kg, so it can be an alternative for consumers who are not likely to install a Roof SPP due to the roof’s static condition under normal conditions. In addition, flexible solar panels can be easily shaped and adapted to the shape of the roof, thus requiring much less conventional construction.
This technology is still on the way to progress. It has shortcomings in terms of durability compared to monocrystalline or polycrystalline module. In addition, it is lower in efficiency compared to other cell technologies, but many studies are being carried out to improve efficiency.
