Question

How energy is obtained from solar cells?​

Answer 1

Answer:

Many solar panels use silicon, one of the planet’s most common elements. But since creating silicon crystals of suitable quality is difficult and expensive, home solar systems are usually built from similar, but less expensive materials, such as copper, indium, gallium and and selenide These aren’t as efficient as high-quality silicon, but still provide adequate power at a reasonable cost.

Solar panels use the photons produced by sunlight to generate direct current (DC) electricity. When the photons hit the panel they are absorbed by the panel's semiconducting silicon material. During this process electrons separate from the atoms and move around the solar cell.
