Context triple: [Michael Grätzel, knownFor, dye-sensitized solar cell]
  • A. Shockley–Queisser limit
    The Shockley–Queisser limit is a theoretical maximum efficiency for single-junction solar cells, defining the upper bound on how much sunlight can be converted into electricity under standard conditions.
  • B. DSC
    DSC is a widely used introductory textbook on database systems that covers fundamental concepts such as data models, SQL, and database design.
  • C. DSC
    The Distinguished Service Cross (DSC) is a high-level military decoration awarded for extraordinary heroism in combat, primarily associated with the United States Army.
  • D. Esaki diode
    The Esaki diode is a heavily doped semiconductor tunnel diode that exhibits negative differential resistance, enabling high-speed and microwave-frequency electronic applications.
  • E. SolarWorld (historically)
    SolarWorld was a major solar panel manufacturing company that once operated one of the largest solar production facilities in Hillsboro, Oregon, and was a significant employer in the region.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
