monocrystalline |
monocrystalline |
To make solar cells for monocrystalline solar panels, silicon is formed into bars and cut into wafers. These types of panels are called “monocrystalline” to indicate that the silicon used is single-crystal silicon. |
|
polycrystalline |
polycrystalline |
Polycrystalline solar panels are also referred to as “multi-crystalline,” or many-crystal silicon. |
|
amorphous |
amorphous |
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. |
