What Are Nanocrystal Solar Cells?
Nanocrystal solar cells, also known as quantum dot solar cells, are a type of photovoltaic cell that uses semiconductor nanocrystals to convert sunlight into electricity. These nanocrystals—tiny particles typically between 2-10 nanometers in size—are made from various materials like cadmium selenide (CdSe), cadmium telluride (CdTe), and lead sulfide (PbS). Their key feature lies in their ability to absorb light over a wide spectrum and convert it into electricity more efficiently than traditional solar technologies.
Unlike conventional solar cells that use silicon or thin-film materials, nanocrystal solar cells can be tuned to absorb different wavelengths of light, which improves their efficiency. This is because the size of the nanocrystals can be precisely controlled to modify their electronic properties, leading to enhanced light absorption and energy conversion.
