What are Flexible Solar Panels?
Flexible solar panels are a type of photovoltaic panel that can be bent and molded to fit various surfaces, including curved and irregular shapes. Their manufacturing process usually involves the usage of thin-film solar cells. These solar cells are embedded into a flexible substrate, such as plastic or metal. The thin-film solar cells are much lighter and thinner than traditional solar cells, making them more versatile and easier to install.
The monocrystalline and Polycrystalline panels are manufactured by using silicon wafers. The thickness of these panels is usually slightly thicker than the human hair which is 200 micrometers thick. To manufacture bendable solar panels, the silicon wafers are sliced up to a few micrometers. These ultra-thin silicon sheets provide these panels with their flexible nature.
Tehse solar panels with ultra-thin layers of silicon cells are around from a decade. Moreover, the research at the Massachusetts Institute of Technology is taking organic solar cells to a whole new level. The research shows that instead of utilizing silicon in solar cells, electrodes of graphene can prove more beneficial for the generation of solar energy. So far, the brittleness of the electrodes was the main concerning factor for the flexibility of solar panels. But graphene electrode is groundbreaking technology to avoid problems like brittleness. With the help of this technology, we can manufacture thinner, more flexible, and more stable panels.
Types of Flexible Solar Panels:
Both flexible and standard panels make use of photovoltaic solar cells for energy production purposes. However, the standard panels are thicker, heavier, and are more durable. The traditional panels usually have a rigid structure and more glass layers in comparison to bendable panels. The flexible solar panels are less durable but they are quite easy to install.
Currently, in U.S. solar market, two types of flexible solar panels are available. The first type is a thin film. In these panels, the photovoltaic silicon layer is printed on a flexible surface. However, in crystalline solar panels, silicon is sliced into thin sheets. These thin silicon wafers are the main reason that flexible panels have their signature bendability. Nowadays crystalline flexible panels are gaining traction in the U.S. solar market.
What Is the Difference Between Flexible Solar Panels and The Standard Solar System?
The main difference between flexible solar panels and standard solar systems is the design and structure of the panels.
