Since the creation of the first silicon solar cell 70 years ago, solar leaders have been innovating, improving efficiency, lowering costs, and growing this American-born technology into an essential part of our nation’s energy system.In 2023, solar accounted for over 50% of new electricity generating capacity added to the grid and employs over 260,000 Americans. With over 179 GW of installed capacity and growing, the solar and storage industry has become an American energy powerhouse.
The Solar Energy Industries Association has been at the forefront of the solar revolution for the last 50 years. As SEIA continues to fight for the expansion of reliable, low-cost solar power, here is a look back at significant solar milestones over the last 70 years.In April 1954, Daryl Chapin, Calvin Fuller, and Gerald Pearson made the first silicon-based solar cell at Bell Laboratories in Murray Hill, New Jersey.
On April 26, 1954, The New York Times covered the story on its front page. The article called the invention “the beginning of a new era, leading eventually to the realization of one of mankind’s most cherished dreams — the harnessing of the almost limitless energy of the sun for the uses of civilization.”Hoffman Electronics, a manufacturer of radios, televisions, and solar cells, contributed several early breakthroughs in solar cell efficiency.
As research on solar energy continued, governments began considering its implications on an international scale. The United Nations held a conference on applications of solar, wind, and geothermal energy in Rome from August 21–31, 1961. About half of all papers that were presented at the conference discussed applications of solar energy, showcasing an international effort to develop solar power.Alongside early developments in clean, solar energy came an increasing concern for the environment.
Solar is the fastest-growing sector of the energy industry, and SEIA will continue to lead the way to deliver greater economic opportunities, lower energy bills, and a more resilient and reliable grid.We publish a number of guest posts from experts in a large variety of fields.
