It shows how heterojunction cells are constructed by combining the architecture of an amorphous cell and a crystalline cell. The efficient amorphous surface passivation layers p-i and i-n are used to passivate the crystalline silicon bulk. Amorphous cells are very thin (<1 μm), whereas conventional crystalline cells have typically a …
Learn MoreThe so-called first-generation crystalline silicon PV cells are the commercial PV modules basis acting as the semiconductor material with a thickness of about 200 μm. Two types of cells are distinguished as illustrated by Fig. 4.3. The mono-crystalline silicon cells have a perfectly arranged crystalline structure with a dark gray color.
