Subject- Chemistry

UV solar cell. The ultraviolet range of the solar spectrum corresponds to wavelengths from about 10 to 390 nm, that our eyes can't see. (Many other animals, like butterflies, can see ultraviolet light, by the way.) Note that "nm" is nanometers, or 10-9 m. The visible range is about 390 nm to 700 nm. Suppose one made a semiconductor with a bandgap that corresponded to a 390 nm photon. What would its bandgap energy be, in eV?
