  • Patent number: 9818888
    Abstract: A method of forming a coating layer on a glass substrate in a glass manufacturing process includes: providing a first coating precursor material for a selected coating layer composition to at least one multislot coater to form a first coating region of the selected coating layer; and providing a second coating precursor material for the selected coating layer composition to the multislot coater to form a second coating region of the selected coating layer over the first region. The first coating precursor material is different than the second precursor coating material.

  • Publication number: 20130020539
    Abstract: A novel multiband absorption based solar cell is disclosed by using the europium chalcogenides (EuX, X?O, S, Se, Te) and related magnetic semiconductor materials, in which an intermediate band is formed by the localized Eu 4f electrons between p-states of chalcogen ions and Eu s-d states. The energy gaps among the multibands can be in the spectral range of the sunlight, thus they can serve as better sunlight absorbers in solar cells than the conventional single band-gap semiconductors such as Si and GaAs. With these multiband semiconductors, the bottleneck in current power conversion efficiency can be potentially overcome in single junction photovoltaics.
