How do solar panels pv cells work.

Photovoltaic cells are made of special materials called semiconductors such as silicon which is currently used most commonly. Solar panels actually comprise many smaller units. Modules are designed to supply electricity at a certain voltage such as a common 12 volts system. 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.

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. Basically when light strikes the cell a certain portion of it is absorbed within the semiconductor material. 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. The current produced is directly dependent on how much light strikes the module.

A number of solar cells electrically connected to each other and mounted in a support structure or frame is called a photovoltaic module. This means that the energy of the absorbed light is transferred to the semiconductor. Solar pv cells generate electricity by absorbing sunlight and using that light energy to create an electrical current.
