The fundamental building block of any solar panel circuit is the photovoltaic (PV) cell, which converts incident photons into electrical energy via the photovoltaic effect. A PV cell operates as a p-n junction semiconductor, where electron-hole pairs are generated upon photon. . The purpose of this talk is to inform and remind the students beginning to construct solar panel projects how circuits behave so they can appropriately wire up the panels. This is suitable for high school students. When photons with energy Ephoton ≥ Eg (where Eg is the bandgap energy) strike a semiconductor, they excite electrons from the valence band to the conduction band. Along with other clean energy sources like wind power and hydropower, solar is a vital component of a growing base of renewable energy sources. Solar panels generate electricity by a process that involves the use of some important pieces of equipment and physical phenomena.
