How Do Solar Panels Pv Cells Work

Solar panels work by absorbing sunlight with photovoltaic cells generating direct current dc energy and then converting it to usable alternating current ac energy with the help of inverter technology.

How do solar panels pv cells work.

Individual solar cell devices are often the. A solar cell or photovoltaic cell is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect which is a physical and chemical phenomenon. Modules are designed to supply electricity at a certain voltage such as a common 12 volts system. Solar pv cells generate electricity by absorbing sunlight and using that light energy to create an electrical current.

Photovoltaic cells are made of special materials called semiconductors such as silicon which is currently used most commonly. It is a form of photoelectric cell defined as a device whose electrical characteristics such as current voltage or resistance vary when exposed to light. The current produced is directly dependent on how much light strikes the module. This means that the energy of the absorbed light is transferred to the semiconductor.

There are many photovoltaic cells within a single solar panel and the current created by all of the cells together adds up to enough electricity to help power your home. Ac energy then flows through the home s electrical panel and is distributed accordingly. Basically when light strikes the cell a certain portion of it is absorbed within the semiconductor material.
