Timeline for Thin Film Solar Cell |
|
| In 1841, Edmund Becquerel, the son of a physicist
and the father of another one, generated electricity by illuminating
an electrode with different types of light, including sunlight |
 |
| In 1875, American, G.R. Carey invented the phototube. The light-sensitive photo-cathode consist of a thin film. Under illumination, low work-function metals, such as cesium, will release energetic electrons from the cathode. |  |
