Topic: Electronic Devices
For obtaining maximum power from a solar cell, it should operate on which portion of its V-I characteristics?
- A. Flat portion
- B. Knee
- C. Falling portion
- D. None of the above
Answer: B. Knee
Explanation: The maximum power point (MPP) of a solar cell's V-I characteristic curve occurs at the "knee" of the curve. This is the point where the product of voltage and current ($P = V \times I$) is at its absolute maximum, balancing high voltage with high current before the current drops off rapidly.
