What is a solar cell

Solar cells are made of various semiconductor materials, similar to how computer chips are made of silicon. computer. Semiconductors are materials that have electrical conductivity between conductors (often called metals) and insulators such as ceramics and glass. They are usually made of pure elements such as silicon or germanium. They are helpful because deliberately adding impurities can easily manipulate their behavior. By adding impurities, or doping, you can adjust the number of holes and electrons in the semiconductor. A semiconductor with more holes is called a P-type semiconductor, and a semiconductor with more electrons is called an N-type semiconductor. The combination of p-type and n-type semiconductors is called a PN junction. So when photons strike a PN junction semiconductor or silicon solar cell, the energy is absorbed and electrons flow through the material in the solar cell. This flow of electrons through the solar cell can be extracted as electrical energy through the grid lines of the solar cell.



What is a solar panel

A solar panel, also known as a solar panel module, is a group of solar cells mounted on a frame prepared for solar installations. A collection of these modules or solar panels is called an array, and when an array is mounted to a roof or installed in an open area, it is called a solar system. Most solar panels used in rooftop solar installations have 60 cells connected in series. Meanwhile, a standard commercial solar panel consists of 72 cells.
