4 FAQs about Photovoltaic panel PN junction manufacturing process

What is a PN junction solar cell?

The chapter presents the physics of the p‐n junction solar cell which is common to a wide range of semiconductor materials. Light that enters the p‐n junction and reaches the depletion region of the solar cell generates electron‐hole pairs (EHPs). A photodiode is a light detector that operates in reverse bias.

Are pn junctions photovoltaic?

What is not commonly known is that most PN junctions are photovoltaic. While solar cells are made with a large area PN junction, a LED has only a small surface area in comparison. We can show the photovoltaic effect by wiring 10 LED's in parallel. When exposed to sunlight, the LED's will clearly generate electric current.

What is a PN junction?

Summary This chapter focuses specifically on p‐n junctions designed as solar cells for photovoltaic (PV) electricity production. It explores the basic operation of inorganic p‐n junctions specifically designed and optimised for solar cells.

How to choose a solar cell p-n junction?

Ideally, an efficient solar cell should have a large shunt resistance and a small series resistance. Both types of para-sitic resistances can reduce the performance of the solar cell p-n junction.
