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.
From the source of energy to the end consumer, in whatever form, and all the conversion in between, it is semiconductor technology which has brought about a sea change. In the next few paragraphs, the role of semiconductors is highlighted in the solar/alternate energy value chain.
Solar or photovoltaics (PV) provide the convenience for battery charging, owing to the high available power density of 100 mW cm −2 in sunlight outdoors. Sustainable, clean energy has driven the development of advanced technologies such as battery-based electric vehicles, renewables, and smart grids.
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.
Semiconductors play a critical role in clean energy technologies that enable energy generation from renewable and clean sources.
