Customer ServiceWhat is UVB phototherapy? Ultraviolet B (UVB) phototherapy delivers shortwave ultraviolet radiation to treat skin conditions such as psoriasis.Phototherapy works by suppressing DNA synthesis, which in turn reduces inflammation.. Narrowband UVB phototherapy (311–312 nm) is increasingly used compared to broadband UVB phototherapy (270–350 nm).
Customer ServiceThe presence of UV light is vital for maximizing solar panel performance. Without UV rays, solar panels would not be able to generate the same level of electrical output, resulting in decreased energy production. This is why it''s crucial to consider the impact of UV light when designing solar panel systems.

Customer ServiceWe all know that too much sun is bad for your skin. But how do you know how long you can stay in the sun? You can''t see or feel UV light, so it''s difficult to know how strong it is and what effect it will have. Summer heat isn''t a good indicator here because UV radiation might also be present when it''s cold outside. This is because heat from the sun doesn''t come from
Customer ServiceWhile a small fraction of sunlight comprises ultraviolet (UV) light, it contains high-energy photons that can be harnessed by solar panels for energy generation. Despite UV light carrying more energy per photon than visible light, its limited presence in the overall sunlight reaching Earth makes it a less efficient choice for solar energy

They have the capacity to convert the energy from UV light into electricity. This contributes to the overall energy output of solar panels. While a small fraction of sunlight comprises ultraviolet (UV) light, it contains high-energy photons that can be harnessed by solar panels for energy generation.
Waves of solar energy radiate, or spread out, from the Sun and travel at the speed of light through the vacuum of space as electromagnetic radiation. The majority of the Sun’s radiation reaching Earth is in the form of visible light we can see and invisible infrared energy that we can’t see.
The intensity of UV light decreases as you move farther from the equator, which can have an impact on the overall efficiency of solar panels. Areas closer to the equator receive more direct sunlight and higher levels of UV light, making them more favorable for solar energy production.
Each solar cell has two sets of metal gridlines connected to its surface, called fingers and busbars. The electricity is collected in the fingers, which are the very thin set of metal gridlines that run up and down the solar cell. The fingers route the electricity to the busbars, which run perpendicular to the fingers.
