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.. Solar cell When sunlight strikes a solar cell, an electron is freed by the photoelectric effect. This energy can be used to generate electricity or be stored in batteries or thermal storage. Below, you can find resources and information on the. . Solar energy can be harnessed two primary ways: photovoltaics (PVs) are semiconductors that generate electricity directly from sunlight, while solar thermal technologies use sunlight to heat water for domestic uses, to warm buildings, or heat fluids to drive electricity-generating turbines.
