How do solar cells work?

Working Principle: The working of solar cells involves light photons creating electron-hole pairs at the p-n junction, generating a voltage capable of driving a current across a connected load.

How do solar cells convert light into electricity?

Solar cells convert light from the sun directly into electricity. Sunlight is made up of tiny packets of energy called photons. When sunlight hits a solar cell, the photons knock free minute particles called electrons contained inside. As the electrons begin to move about they are 'routed' into a current.

How many volts can a solar cell produce?

Individual solar cells can be combined to form modules commonly known as solar panels. The common single junction silicon solar cell can produce a maximum open-circuit voltage of approximately 0.5 to 0.6 volts. By itself this isn’t much – but remember these solar cells are tiny.

What is a solar cell?

A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. A solar cell is basically a p-n junction diode.

What is a video cut of a solar array?

Video cuts to animation of panel rotating around sun, then fades to footage of satellite flying over Earth. Narrator: In the next decade, solar arrays found their first significant application on spacecraft. Video cuts to television with President Jimmy Carter on screen.

What are solar cells made of?

Construction Details: Solar cells consist of a thin p-type semiconductor layer atop a thicker n-type layer, with electrodes that allow light penetration and energy capture.
