Latest Invention: Solar-Powered Circuit


Researchers from the University of Pennsylvania managed to come up with a special circuit that in future can become one of the most important inventions in the science. They created the world's first photovoltaic circuit that can generate electricity by harnessing solar energy. Their latest invention could be used to power various consumer devices.

According to Dawn Bonnell, a researcher from the University of Pennsylvania, the breakthrough could lead to the development of a new generation of optical and electronic gadgets.

At the moment Bonnel and her team are able to generate a rather small amount of energy, which is not be enough to power electrical devices. However, scientists consider that there are different ways of boosting the production electricity from light. For example it would be possible to stack several layers of light-collecting and power-using circuits.

Most likely the new type of circuits will not be able to replace silicon counterparts, but they can be used to power different small robotic devices, informs Discovery News. Currently the new circuit can transform light into electricity and Lukas Novotny, a researcher at the Institute of Optics at the University of Rochester thought that it would be possible to make a completely new type of lighting materials if the latest invention of scientists from the University of Pennsylvania could turn electricity into light.
