This section will introduce and detail the basic characteristics and operating principles of crystalline silicon PV cells as some considerations for designing systems using PV cells. A PV cell is essentially a large-area p–n semiconductor junction that captures the energy from photons to create electrical energy.
The basic structure of a PV cell can be broken down and modeled as basic electrical components. Figure 4 shows the semiconductor p–n junction and the various components that make up a PV cell.
The photovoltaic (PV) cell is the heart of the solar panel and consists of two layers made up of semiconductor materials such as monocrystalline silicon or polycrystalline silicon. A thin anti reflective layer is applied to the top of these layers to prevent light reflection and further increase efficiency.
PV cells are wafers made of crystalline semiconductors covered with a grid of electrically conductive metal traces. Many of the photons reaching a PV cell have energies greater than the amount needed to excite the electrons into a conductive state. The extra energy imparts heat into the crystalline structure of the cell.
Photovoltaic (PV) cells, or solar cells, are semiconductor devices that convert solar energy directly into DC electric energy. In the 1950s, PV cells were initially used for space applications to power satellites, but in the 1970s, they began also to be used for terrestrial applications.
Photovoltaic panels are made up of several groups of photoelectric cells connected to each other. Each group of solar cells forms a network of photovoltaic cells connected in a series of electrical circuits to increase the output voltage.
