Magnesium fluoride (MgF2), an alkaline earth metal salt, has a long history of being utilized in optical devices, including c-Si solar cells. Its high transparency and low refractive index (n≈1.36) have proven useful on the front surface of such devices as an inexpensive second−layer antireflection coating. In fact, several world-record crystalline silicon solar cells used such a layer in addition to zinc sulfide, a combination of optical layers that can minimize reflection losses. In addition, due to its relatively high threshold to laser-induced damage, high hardness, and excellent stability in hostile environments, such films have also been utilized for optical components in high power lasers. Another important use of MgF2 is as an evaporated coating onto aluminum, where it greatly increases the Vacuum Ultra-Violet (VUV) reflectance and also retards oxidation.
