JAN 23 What is a Cell Junction?

A cell junction is the region of direct contact between the two photovoltaic cell layers (positive and negative). The junction is located in the middle of the depletion zone or cell barrier.

Which Type of Junction is Used in Solar Cells?

The single-junction form of conventional solar cells used in solar power plants uses a single p-n junction to produce electricity. A single p-n junction is made in a solar cell by “doping” one side with boron, the p-type, and the other side with phosphorus, the n-type.

What is a PN Junction?

In order to generate voltage and useful work, a p-n junction separates the electron and hole carriers in a solar cell. Other methods of extracting carriers from a solar cell include metal-insulator-semiconductor contacts or even carrier-selective contacts. The analysis serves as a foundation for various devices, although a pn junction is the one that is most frequently used.

How Many Junctions Does a Solar Cell Have?

Solar cells involve multi junctions, among which triple junctions are the most common. On germanium wafers, it is possible to build triple junction cells made of indium gallium phosphide (InGaP), gallium arsenide (GaAs), or indium gallium arsenide (InGaAs), and germanium (Ge).
