SOLAR SYSTEM

Detailed explanation-1: -At solar minimum, solar ultraviolet radiation decreases, but the effect of this primarily hits the stratosphere and higher altitudes. It causes Earth’s atmosphere to shrink slightly, which reduces drag on satellites.

Detailed explanation-2: -“Solar cell performance is also adversely affected by UV radiation through the generation of surface defects.” Within a silicon solar cell, the UV light can cause damage to the passivation layers, to the silicon beneath, and at the interface between the two.

Detailed explanation-3: -The sun produces UV, which is commonly split into three bands: UVA, UVB, and UVC. UVA is not absorbed by ozone. UVB is mostly absorbed by ozone, although some reaches the Earth. UVC is completely absorbed by ozone and normal oxygen.

Detailed explanation-4: -Ozone is extremely valuable since it absorbs a range of ultraviolet energy. When an ozone molecule absorbs even low-energy ultraviolet radiation, it splits into an ordinary oxygen molecule and a free oxygen atom. Usually this free oxygen atom quickly re-joins with an oxygen molecule to form another ozone molecule.
