The pn junction
WebbThe PN junction A PN junction is simply a piece of semiconductor which is doped n-type on one side and p-type on the other. In a PN junction which is forward biased (Fig. 16.3) the current which flows is almost entirely due to majority carriers. Under reverse bias however, the current, which is very much smaller than Webb26 dec. 2024 · In this video we'll fill in the last missing pieces in order to understand completely how a solar cell works.

Webbp-n junction, in electronics, the interface within diodes, transistors, and other semiconductor devices between two different types of materials called p -type and n -type semiconductors. These materials are formed by the deliberate addition of impurities to pure semiconductor materials, such as silicon. WebbThe pn Junction and the Semiconductor Diode. When we’re focusing on the physics of semiconductor operation, we use the term pn junction; when we’re focusing on circuit design, we use the term diode. But they’re essentially the same thing: a basic semiconductor diode is a pn junction with conductive terminals attached.
WebbPN junction definition: Using different doping processes, the P-type semiconductor and the N-type semiconductor are fabricated on the same semiconductor (usually silicon or germanium) substrate through diffusion, and a space charge region is formed at their interface called a PN junction.
