An amorphous semiconductor is a glassy or disordered form of crystalline semiconductor material. Such conductors have a network structure with primarily covalent bonding.
What are Two Widely Studied Amorphous Semiconductor?
a-Si and amorphous selenium, a-Se are the two most widely studied amorphous semiconductors. Usually, by evaporation or sputtering, both Si and Se can be made into glassy form. In both these forms, most atoms have a normal valence. However, they have several irregularities and defects in the structure.
What is the Application of Amorphous Semiconductors?
Amorphous semiconductors are non-crystalline semiconductor materials and they are mostly used in PV panel construction. Compared to crystalline, they are cheaper and easier to manufacture. However, their downside is that they are less efficient and also degrade over time.

What are Amorphous Silicon Solar Panels?
Amorphous silicon solar panels are also referred to as thin-film solar panels. They are perfect for applications that require little electricity, such as wristwatches and pocket calculators. These panels don’t have crystalline silicon and thus have no structured layers. They are made up of silicon materials that are both formless and shapeless in composition.
