Fotokäyttöisissä
Fotokäyttöisissä is a Finnish term that translates to "photoelectric" or "photovoltaic" in English. It refers to phenomena, devices, or systems that utilize the photoelectric effect. The photoelectric effect is a physical process where photons (light particles) interact with a material, causing electrons to be emitted. This interaction can lead to the generation of an electric current or a change in the material's electrical properties.
Devices that are "fotokäyttöisissä" often rely on semiconductors. When light strikes a semiconductor material within such
