The P-N Junction Photovoltaic Principle
A solar cell''s core is a p-n junction, an interface between p-type and n-type semiconductor materials. This junction creates a built-in electric field in a depletion region. When photons with sufficient energy
SEMICONDUCTORS AND P-N JUNCTIONS
P-N JUNCTIONS 2.1 SEMICONDUCTORS In 1839 Becquerel observed that certain materials, when exposed to light, produced an el. ctric current (Becquerel, 1839). This is now known as the
6.4: pn Junctions
This page explains the importance of pn junctions in semiconductor devices such as photovoltaic cells, LEDs, and photodetectors. It covers their construction, behavior, and the charge carrier
How Photovoltaic Cells Generate Electricity
A solar cell is essential a PN junction with a large surface area. The N-type material is kept thin to allow light to pass through to the PN junction. Light travels in packets of energy called photons. The
What Is a P-N Junction and How Does It Work in a Solar Cell?
What Is a P-N Junction and How Does It Work in a Solar Cell? A p-n junction is the interface between a p-type and an n-type semiconductor material. It is the fundamental building block
