Photosensitivity
The feature of certain types of materials that change their physical or chemical properties upon the impact of a photon. They can be designed to absorb light of only certain wavelengths. Photosensitive materials are used to make photodiodes, photodetectors, or solar cells.
Thin film solar cells contain photosensitive materials like amorphous silicon. (Source: © iaremenko / stock.adobe.com)
