What is Solar Electricity?

Solar Electricity Definition

Solar electricity is produced by sunlight hitting photovoltaic cells, generating power.

Photovoltaic Effect

Solar energy electrical engineering relies on the photovoltaic effect, where sunlight creates electricity in semiconductor materials.

Structure of Solar Cells

A solar cell consists of a thin n-type layer on top of a thicker p-type layer, with a depletion region at their junction. 

Charge Separation

Sunlight causes electrons to move to the n-layer and holes to the p-layer, creating a potential difference.

Applications of Solar Electricity

Solar power is ideal for remote locations and moderate power needs, though it is less practical for high-power equipment.
