Solar cells are made from semiconductors with p-n junctions because this structure allows for the efficient conversion of sunlight into electricity. The p-n junction creates an electric field that separates charge carriers (electrons and holes) generated by the absorption of photons. When sunlight strikes the semiconductor, it excites electrons, and the electric field drives these electrons toward the n-type side and holes toward the p-type side, generating a flow of electric current. This fundamental mechanism is crucial for the operation of solar cells, enabling them to convert solar energy into usable electrical energy.

This is very old germanium diode and nomenclature comes before a standard had been established for semiconductors. They modeled 0A after the vaccum tubes where 0 - zero means 0Volts filament voltage and A meant single diode. Latter , semiconductor nomenclature come where the first number was telling a number of PN junctions followed by N (this is for US), Japanese and Europeans had different naming standards
PN means pressure rating of a pipe....PN is just a symbolic representation....
A PN diode is a semiconductor device that allows current to flow primarily in one direction. It consists of a p-type region (with positive charge carriers, or holes) and an n-type region (with negative charge carriers, or electrons). When forward-biased, the diode conducts current, while in reverse bias, it blocks current flow. This property makes PN diodes essential for rectification, signal modulation, and various electronic applications.
Resistor in IC are made of semiconductor structures in a manner similar to transistors and PN junctions
a nonhomogenous distribution of current density through a conductor or semiconductor, especially at the vicinity of the contacts and over the PN junctions.

A PN junction is a semiconductor device that acts as a diode, allowing current to flow in one direction while blocking it in the other. It is the basis of many electronic components like diodes, transistors, and solar cells. The junction creates a depletion region that helps control the flow of electric current.

There are two semiconductor junctions. Transistors are designated as NPN or PNP and a diode is an NP or PN junction depending on direction of current flow. However, the function of a transistor is different than two back to back diodes.
The voltage across a forward-biased PN junction in a semiconductor diode or transistor.
A PNP transistor is a bipolar transistor formed by two opposing PN junctions in close proximity.
Diode is made of P and N type semiconductors having PN junction. The question is meanigless.
A PN junction diode is a non-linear component and it consists of two junctions namely P-junction & N-junction where the majority and minority charge carriers are present like electrons and holes. It is also known as a semiconductor diode or PN junction diode. This diode includes two terminals namely anode and cathode, where a p-type semiconductor is an anode (positive voltage) and N-type semiconductors are cathode (negative voltage). The flow of current in the diode is in one direction only because it opposes in another direction with high resistance.

A diode has a n type and a p type materials that's why it's called a pn-junction device
