| 1. | :I think you are confusing the photovoltaic effect with the photoelectric effect.
|
| 2. | Photovoltaic cells convert light into an electric current using the photovoltaic effect.
|
| 3. | Solar cells are devices that convert sunlight into electricity by the photovoltaic effect.
|
| 4. | This is specifically called the bulk photovoltaic effect, and occurs because of non-centrosymmetry.
|
| 5. | Adams and Day observed the photovoltaic effect in selenium in 1876.
|
| 6. | The photovoltaic effect is closely related to the photoelectric effect.
|
| 7. | Photovoltaic effect can be achieved in ideal single wall carbon nanotube ( SWNT ) diodes.
|
| 8. | Whether direct excitation or thermal effects dominate the photovoltaic effect will depend on many material parameters.
|
| 9. | The addition of junction-forming layers, however, induces a built-in electric field that produces the photovoltaic effect.
|
| 10. | Because of this work, the photovoltaic effect has also been known as the " Becquerel effect ".
