SOlAR PhOtOVOltAIC (“PV”) SySteMS – An OVeRVIew For crystalline silicon PV modules, the module efficiency is lower compared to the sum of the component cell efficiencydue to the presence of gaps between the cells and the border around the circuit i.e., wasted space that does not generate any power hence lower total efficiency. the surface of the solar cell wit hout much loss. • Balance of System – Several source circuits will terminate in a master combiner box, and feed a central inverter. The cell can be considered as a two terminal device which conducts like a diode in the dark and generates a photovoltage when charged by the sun. While n-type semiconductor and p-type semiconductor contact each other, the free electrons near to the contact surface of n-type semiconductor get plenty of adjacent holes of p-type material.
