Bell Labs 1954 Solar Panel

Sixty years ago scientists at bell labs in new jersey announced that the world finally had an efficient way to turn sunlight into electricity.

Bell labs 1954 solar panel.

At first they didn t understand how the process worked. Boasting an anemic one percent efficiency they could hardly keep a few lightbulbs shining much less power entire homes. The first solar panels as most of us would recognize them were invented in bell labs in 1954 during some of the worst smog years in los angeles. 1954 1954 photovoltaic technology is born in the united states when daryl chapin calvin fuller and gerald pearson develop the silicon photovoltaic pv cell at bell labs the first solar cell capable of converting enough of the sun s energy into power to run everyday electrical equipment.

On april 25 1954 bell labs announced its latest invention a silicon solar cell at a press conference in murray hill new jersey. Fuller at work diffusing boron into silicon to create the world s first solar cell solar cells which convert sunlight into electrical current had their beginnings more than a hundred years ago though early solar cells were too inefficient to be of much use. The bell solar battery was installed on a part of this trial system in october 1955 as an experimental substitute for ordinary batteries. At that time however solar panels were more of an amusing novelty.

April 25 1954 bell labs introduces the modern silicon solar cell by powering a miniature ferris wheel. A hush fell over the audience during a demonstration of the nation s first solar panel used to power a toy ferris wheel and a radio transmitter.

History of the modern silicon solar cell. Scientists had observed the ability of some materials to generate electricity from light as far back as 1839. These cells have about 6 efficiency.
