Additionally, they produce the highest amount of electricity per square foot, making them the most efficient choice.
Monocrystalline solar panels are also the most durable and can last over 25 years with minimal loss in efficiency. However, they are also the most expensive option and may not be as suitable for larger applications due to the higher cost.
What are 3 photovoltaic cells?
Photovoltaic (PV) cells are a type of semiconductor technology commonly used in solar panels to transform solar energy into direct current electricity. They are also referred to as solar cells. Photovoltaic cells are made up of multiple layers of semi-conducting material, typically silicon, combined with other elements to produce an electric field in certain conditions.
When light strikes the surface of the PV cell, electrons in the material become energised and flow, generating an electric current.
There are three main types of PV cells: monocrystalline, polycrystalline, and thin-film. Monocrystalline requires a higher production cost than other PV cells, but has the highest efficiency, meaning the power output relative to the input is higher.
Polycrystalline is a much cheaper alternative, and has slightly lower efficiency rates than monocrystalline, but is more suitable for larger applications due to its lower price. Thin-film PV cells have the lowest efficiency, but are the cheapest option and well-suited for small scale applications.
In summary, the three types of photovoltaic cells are monocrystalline, polycrystalline and thin-film. Monocrystalline has the highest efficiency while polycrystalline and thin-film offer lower costs and lower efficiency.
