Flexible varieties of these devices are made by depositing CIGS on a molybdenum backing.
Flexible varieties of these devices are made by depositing CIGS on a molybdenum backing. The maximum efficiency for these devices is given by the ShockleyÂ–Queisser limit, which can be overcome by using multiple junctions and ensuring the band gaps of the materials used range from largest to smallest. An important factor in determining the efficacy of these devices is ratio of maximum obtainable power to the the product of open circuit voltage and short circuit current, known as the fill factor. They are most often fabricated from polycrystalline silicon with large grain sizes. For 10 points, name these devices that convert sunlight into electrical energy.
