The best solar cells can wring out nearly half that light energy as electricity. It happens like this: A photon from the sun strikes the solar panel's photoactive layer, which "knocks" an electron ...

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their ...

When she’s not working, Sabrina enjoys creative ... Solar trees use the same physical principle as regular PV systems. An array of solar cells is exposed to sunlight, and they generate direct ...

Japanese physicists have developed a stretchable solar cell that could power wearables in the future without sacrificing power conversion efficiency. The team from Riken, a Japanese scientific ...

Research provides a deeper understanding of precisely what is happening in organic solar cells as light is converted into electricity. Researchers developed a new method which visualizes interfaces ...

The solar cell was coming into form. Building on the existing principles of the photovoltaic effect ... A year later, Aleksandr Stoletov had built a working photoelectric cell, the first of its kind.
