First modern solar cell

The first modern solar cell In 1954, the first modern silicon cells raised by Bell Labs, then it shown at the National Academic of Science meeting. Moreover, this kind of cell can make 6 percent efficiency. Then, the New York Time come up with that the cell would lead to a source of â€Å"Limitless energy of the sun†. In 1955, the Western Electric created very significant solar cell technologies. The technology start to use in makes solar cells. In 1957, the AT&T telecom company used the â€Å"solar battery' for their cell phones. Hoffman Electronics created about 8 percent efficient solar cell.Thinking about investing in a solar array but concerned about the lifespan of photovoltaic cells? Consider this: the world's oldest solar panel † a 60 year-old crystal ball-like contraption † still works. The panel was built by a British science teacher who wanted to prove the novel idea that sunlight could be converted into electricity. Of course, the panel doesn't produce much electricity-Just 1. 5 volts of electricity in direct sunlight, or enough to power a digital watch. And while todays panels only need indirect sunlight to function, the 60 year-old version requires direct sunlight.Still, the selenium-based panel is surprisingly similar to current models. The half century-old device is the first example of a modern solar panel, but it isn't the first piece of solar technology. That distinction goes to Charles Fritts, who built the first solar cell in 1883. Want to check out the panel for yourself? It's currently on display at Antiques for Everyone, a British antique event.
