Solar cells run well after 60 years of hiding

Fred Nickson, an Aussie antique dealer, has discovered a solar cell-type device, after 60 years of operation, still works well.

The device was originally a product of a science teacher, built to prove the reality of the process of converting solar energy into electricity. The machine was completed around 1950.

The device was bought by antique dealer Fred Nickson from the distant relative of the teacher. In the appearance of a glass globe, placed under the sun, the device produces a 1.5V electric current.

The 60-year antique model of the machine still works well.

Professor Nickson, of the British National Antiquities Center, commented: "I am really amazed that this device still works perfectly. The machine has the same structure as the solar cell people still have. Using today, using Selenium series to convert solar energy into electricity ".

The first solar-based technology was developed by Charles Fritts in 1883, but this finding was not noticed because of inefficiency.

Later, Russian physicist Aleksandr Stoletov developed the first solar panels based on a more stable photoelectric effect.

But it wasn't until Russell Ohm came up with the idea of ​​solar panels made from semiconductor circuits, releasing electrons when placed under sunlight, thereby creating an electric current.

The newly discovered machine could be nominated as one of the first solar power generation devices.
