Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.
Photovoltaic solar panels are much more common than those that utilize thermal conversion, so we’ll be focusing on PV solar panels. Sunlight strikes the solar cells of the solar panel. Some of the rays of light or photons pass through the outer layers of the cell and into the silicon core.
Silicon is responsible for the transformation of incoming sunlight into electricity. Solar PV cells comprise positive and negative Silicon films which are placed mostly under thin glass. When sunlight falls on the glass and onto the PV cells, the sunlight photons knock the electrons off the Silicon.
The initial step in the process of solar energy conversion involves the absorption of sunlight by the photovoltaic (PV) cells within a solar panel. These cells, constructed from semiconductor materials such as silicon, capture photons from sunlight. When these photons strike the PV cells, they excite electrons, thereby creating an electric current.
Photovoltaic (PV) cells, commonly known as solar cells, are the building blocks of solar panels that convert sunlight directly into electricity. Understanding the construction and working principles of PV cells is essential for appreciating how solar energy systems harness renewable energy.
Solar PV cells comprise positive and negative Silicon films which are placed mostly under thin glass. When sunlight falls on the glass and onto the PV cells, the sunlight photons knock the electrons off the Silicon. The free electrons are attracted to one side of the Silicon cell which creates an electric voltage that is then channeled.
