solar power

Solar radiation may be converted directly into electricity by solar cells (photovoltaic cells). In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors.(See photovoltaic effect.)The power generated by a single photovoltaic cell is

A Brief History of Solar Energy

Modern solar energy is something that many of us are now familiar with. Energy companies, homeowners and businesses are increasingly harnessing the power of the sun to produce electricity using solar power. Despite this, many people might not realise that the history of solar power dates back many centuries. In fact, the use of solar energy dates back as far as

The Past, Present, and Future of Solar Energy: A Comprehensive

The story of solar energy begins in 1839 with the work of French physicist Edmond Becquerel. In experimenting with metal electrodes and electrolyte solutions, Becquerel discovered the photovoltaic effect—the creation of electric current in a material upon exposure to light.

How NASA Uses and Improves Solar Power

But the practice of converting the Sun''s energy into electricity — what we now call solar power — is less than 200 years old. Yet in that short time, solar power has revealed the Sun''s limitless potential to power an increasingly technological society. Since the 1950s, NASA has harnessed the energy of the Sun to power spacecraft and

OverviewPotentialTechnologiesDevelopment and deploymentEconomicsGrid integrationEnvironmental effectsPolitics

Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often

Solar Energy Basics (Text Version) | NREL

The History of Solar Power. Voice Over: Solar energy is the most abundant source of energy on Earth, fueling the plants we use for food and fuel and powering the wind and weather in our skies. Humans first directly harnessed solar power in the 7th century B.C., when a magnifying glass was used to concentrate the sun''s rays to make fire.

space-based solar power

· space-based solar power, the collection in space of solar energy, which is then transmitted as a microwave or laser beam to the ground and converted into electrical energy.. The idea of space-based solar power predates the space age. Konstantin Tsiolkovsky proposed in 1923 that space-based mirrors could beam sunlight to the ground. American science-fiction
