← ScienceWhich issue worsens by mismatched conduction band alignment?
A)Photovoltaic open-circuit voltage decrease✓
B)Catalytic reaction rate increase
C)Fluid viscosity reduces significantly
D)Superconducting critical temperature rises
💡 Explanation
Photovoltaic Voc decreases because Shockley-Queisser limit depends strongly upon the band alignment; increased band offset causes greater potential losses, therefore reduces voltage, rather than any other unrelated effects such as viscosity reduction.
