Solar energy
What are solar cells used in solar energy?
They are wafers of silicon with some heat-treated impurities added to them to give them electrical properties
They are in the form of cells arranged next to each other at a certain angle to exploit the greatest amount of sunlight emitted to produce pure electricity without environmental pollution.
With high capacities, it produces DC electricity, which is the same as that produced from chemically treated batteries, and then this electricity is converted from current
DC to AC current, which we use in our daily lives via an inverter
They were used in the late nineties in space stations and satellites due to their complete dependence on sunlight, their ease of installation, and their few or no malfunctions. All they require is to maintain them from the dust that accumulates on them.
Recently, it has been relied upon heavily in most countries of the world in attempts to rely on pure energy and fill the gap of electricity shortages in some areas.
