How does a PV module work?


Sunlight is a stream of photons. When it falls on a photovoltaic cell, i.e., a P-N junction, it causes the electron-hole pairs to break apart. The released negatively charged electrons and positively charged holes accumulate at opposite poles of the cell, generating a constant flow of voltage. When the electrical circuit is closed, electrons travel from cells connected in rows toward positive holes through metallised contacts to equalise the potential. The electrical current created in this manner can be processed by a photovoltaic inverter or used, for example, to power DC loads.
