The two dissimilar semiconductors possess a natural difference in electric potential (voltage), which causes the electrons to flow through the external circuit, supplying power to the load.

The utility-scale solar industry's relentless pursuit of a lower levelized cost of energy (LCOE) has firmly established the 1500V DC system as the new standard. This shift from 1000V systems allows for longer PV strings, reducing balance-of-system (BOS) costs related to combiner.
