From the earliest days of solar-powered satellites to modern rooftop arrays and utility-scale solar farms, this is the complete history of solar energy—and a look at its exciting potential in the years to come. The story of solar energy begins in 1839 with the work of French physicist Edmond Becquerel.
The first solar-powered satellite, Vanguard 1, has traveled more than 197,000 revolutions around Earth in the 50 years it has been in orbit. This application paved the way for more research to decrease costs and increase production. As oil prices rose in the 1970s, demand for solar power increased.
In the United States, the federal Solar Energy Research Institute (now the National Renewable Energy Laboratory) was created in 1977 to drive innovation in photovoltaics. Germany and Japan also emerged as early leaders in solar technology and manufacturing during this period.
To help you better understand how solar cells came to be, we’ve provided a timeline of the discoveries and inventions that led to their creation. French scientist Edmond Becquerel first discovered the photovoltaic effect in 1839. This process occurs when light is absorbed by a material and creates electrical voltage.
In 1994, the National Renewable Energy Laboratory developed a new solar cell from gallium indium phosphide and gallium arsenide that exceeded 30% conversion efficiency. By the end of the century, the laboratory created thin-film solar cells that converted 32% of the sunlight it collected into usable energy.
Solar energy, the radiant light, and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. From the simple magnifying glasses used in the 7th century B.C. to the sophisticated solar cells of today, the journey of solar energy is a testament to human innovation and resilience.
Understanding Solar Photovoltaic (PV) Power Generation
Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels.
