What is Schottky diode?
What is Schottky diode? A type of diode that has a very low voltage drop, normally ranging between 0.15V and 0.25V. Schottky diode is commonly used as a blocking diode in photovoltaic arrays and modules for power loss minimization. A conventional silicon diode has a voltage drop of 0.7V minimum. ← Back to Solar Energy Glossary
Schottky junction solar cell
In a basic Schottky-junction (Schottky-barrier) solar cell, an interface between a metal and a semiconductor provides the band bending necessary for charge separation. Traditional solar cells are composed of p-type and n-type semiconductor layers sandwiched together, forming the source of built-in voltage (a p-n junction). Due to differing energy levels between the Fermi level of …
