Explore the vital role of semiconductors used in solar cells for efficient energy conversion and the advancement of photovoltaic technology. Our world needs renewable energy, making solar cell materials key in research and innovation. Can silicon keep its top spot in semiconductor used in solar cell tech? Or is it being replaced?
Semiconductors are key in turning sunlight into electricity. They absorb light and free electrons to create an electric current. Inside a solar cell, they make a special junction that helps separate and use this electricity. Why Are Bandgaps Important in Photovoltaic Technology? The bandgap of a material is vital in solar tech.
Semiconductors in PV cells absorb the light’s energy when they are exposed to it and transfer the energy to electrons. The absorbed additional energy allows electrons to flow in form of an electrical current through the semiconductor material.
Among the most efficient and by far the most common semiconductor used is silicon which is found in approximately 90% of modules sold. It was first used in solar cells in 1956 and is considered a key material in solar energy production.
Copper indium gallium diselenide (CIGS) and CdTe are the most common thin-film PV semiconductors used to manufacture thin-film solar cells. Although CdTe cells can be manufactured in a cost-efficient manner, they have a lower efficiency compared to silicon cells.
