Photovoltaic timeline
A photovoltaic cell, also called a PV or solar cell, is a device that converts light (radiant) energy directly into electrical energy. PV cells are usually made from silicon. The first PV cells were very inefficient, converting less than 1% of radiant energy into electricity. Today, some solar cells have a 40% conversion rate.

Photovoltaics
Photovoltaic (PV) technologies – more commonly known as solar panels – generate power using devices that absorb energy from sunlight and convert it into electrical energy through semiconducting materials. These devices, known as solar cells, are then connected to form larger power-generating units known as modules or panels.

Solar Photovoltaic Technology Basics | NREL
Photovoltaics (often shortened as PV) gets its name from the process of converting light (photons) to electricity (voltage), which is called the photovoltaic effect.This phenomenon was first exploited in 1954 by scientists at Bell Laboratories who created a working solar cell made from silicon that generated an electric current when exposed to sunlight.
Solar panel
Solar array mounted on a rooftop. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
Solar cell | Definition, Working Principle, & Development | Britannica
3 days ago· Solar cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect. The majority of solar cells are fabricated from silicon—with increasing efficiency and lowering cost as the materials range from amorphous to polycrystalline to crystalline silicon forms.

History of Solar Energy
The photovoltaic (PV) effect refers to the creation of electricity when a material is exposed to light. The name is a combination of phos (meaning light in Greek) and volta (Volta was the Italian physicist after whom the volt is named). Although the sun''s energy has been used for millenia, the history of solar cells begins in the 1800s.
Who Invented Solar Panels? History of Photovoltaic Cell
The Role of Solar Cells in Space Missions. The 1960s saw solar cells become the top power source for satellites. They were also used in solar system probes.

It all began with Edmond Becquerel, a young physicist working in France, who in 1839 observed and discovered the photovoltaic effect — a process that produces a voltage or electric current when exposed to light or radiant energy. A few decades later, French mathematician Augustin Mouchot was inspired by the physicist’s work.
What is photovoltaics & why is it important?
Though solar energy has found a dynamic and established role in today's clean energy economy, there's a long history behind photovoltaics (PV) that brought the concept of solar energy to fruition.
Where does the word photovoltaic come from?
The term "photovoltaic" comes from the Greek φῶς (phōs) meaning "light", and from "volt", the unit of electromotive force, the volt, which in turn comes from the last name of the Italian physicist Alessandro Volta, inventor of the battery (electrochemical cell).
