Thin-film technology involves the deposition of very thin layers of material, often just a few nanometers to micrometers thick, onto a substrate. This technique is widely used in various applications, including electronics, optics, and solar cells. By controlling the thickness and composition of these films, manufacturers can create materials with specific properties, enhancing performance and efficiency. One common application of thin-film technology is in the production of solar panels, where thin layers of photovoltaic materials convert sunlight into electricity. Additionally, it is used in the creation of semiconductors for microchips, enabling the miniaturization of electronic devices while improving their functionality and energy efficiency.
