Amorphous silicon - Wikipedia
Amorphous silicon (a-Si) is the non-crystalline form of silicon used for solar cells and thin-film transistors in LCDs. Used as semiconductor material for a-Si solar cells, or thin-film silicon solar cells, it is deposited in thin films onto a variety of flexible substrates, such as glass, metal and plastic. Amorphous silicon cells generally ...
Amorphous Silicon - an overview | ScienceDirect Topics
Amorphous silicon refers to a form of silicon that lacks the ordered arrangement of atoms found in a crystalline lattice. It is commonly used in the manufacturing of solar cells due to its ability to absorb sunlight efficiently and its potential for producing cells with an efficiency of around 10%.
While crystalline silicon FET’s are the key enablers for the integrated circuit field, amorphous silicon thin film transistors are the key semiconductor of the large-area electronics field, also known as “macroelectronics.”
Amorphous Silicon - an overview | ScienceDirect Topics
Amorphous silicon is a non-crystalline form of silicon with disordered silicon atoms, known for its high light absorptivity. It is used in thin-film PV cells due to its lower production costs and the ability to be deposited on various substrates like steel, glass, and plastic.
