Let’s understand how does a solar PV module work. Solar energy is a key renewable energy source that has the potential to help humanity overcome various issues. Because of its versatility and numerous benefits to people and the environment, this power source is gaining favour. Climate change has triggered a serious crisis. The reality is that, due to all of the climatic conditions and global warming, the end is not far away.
The atmosphere’s high carbon content makes oceans acidic and kills marine life. Higher temperatures cause polar ice caps to melt, wildlife habitats and sea levels to decrease. Irregular rainfall or rising drought damage farming and the subsistence of the world’s weakest portions.
Solar energy, in various forms, is the source of practically all energy on the planet, and humanity has harnessed it in a variety of ways. Photovoltaic cells are basic gadgets that allow us to harness the sun’s energy in an elegant way. PV devices convert solar energy directly into electricity.
We may lower our carbon footprint and put a halt to the abuse of non-renewable energy sources, resulting in significant reductions in air, water, and land pollution, as well as contributing to sound pollution because PV modules are silent energy producers.
SO HOW DOES IT WORK ACTUALLY?
Silicon is the most important component of a solar cell. Silicon is doped with specific impurities in order to use a solar photovoltaic (PV) cell to capture and convert solar energy into electricity. The concept behind solar cells is that when a photon hits a semiconductor, it ejects an electron, resulting in the formation of two conductors: the free electron and the electron hole. When light strikes the PN junction, photons with energies larger than the bandgap of silicon cells are absorbed, resulting in the formation of electron-hole pairs.
These carriers are separated by electric fields within the junction, resulting in a current proportional to the incidence of solar irradiation. Electricity is generated without making any noise, in an environmentally friendly manner, and with no harmful byproducts.
A solar cell array converts solar energy into usable direct current (DC) electricity. To increase the output voltage, solar cells are connected in series. Solar PV modules are made up of series-connected cells. Now that we understand how does a solar PV module work, you must be keen to know more. Stay tuned for more!
