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.
Solar energy conversion using semiconductors to fabricate photovoltaic devices relies on efficient light absorption, charge separation of electron–hole pair carriers or excitons, and fast transport and charge extraction to counter recombination processes.
Semiconductors play a critical role in clean energy technologies that enable energy generation from renewable and clean sources. This article discusses the role of semiconductors in solar cells/photovoltaic (PV) cells, specifically their function and the types used. Image Credit: Thongsuk7824/Shutterstock.com
Semiconductor devices are key in solar technology. They use special properties to change sunlight into electricity. At the core of a solar panel, the semiconductor junction turns light into power, showing the magic of solar energy. Today, silicon is used in almost all solar modules because it’s dependable and lasts long.
Advances like Photon Enhanced Thermionic Emission (PETE) could lead to even higher efficiencies, up to 50% or more. This shows the great potential in semiconductor technology for solar devices. Dye Sensitized Solar Cells (DSCs) are becoming more popular because of materials like titanium dioxide (TiO2).
This can highly improve a semiconductor’s ability to conduct electricity and increase solar cell efficiency. What Are the Types and Applications of Semiconductors Used in Solar Cells? Semiconductors in solar cells include silicon-based and thin-film types like CdTe. Silicon is great for homes and businesses.
