Photovoltaic (PV) Cell: Structure & Working Principle
Photovoltaic (PV) Cell Working Principle. Sunlight is composed of photons or packets of energy. The sun produces an astonishing amount of energy. The small fraction of the sun''s total energy that reaches the earth is enough to meet all of our power needs many times over if it could be harnessed.
Characteristics and Working of PN Junction Diode
Working of PN Junction Diode If an external potential is applied to the terminals of PN junction, it will alter the potential between the P and N-regions. This potential difference can alter the flow of majority carriers, so that the PN junction can be used as an opportunity for the diffusion of electrons and holes.
