Identify the solar cell characteristics from the following options :

The figure, in words

Four I vs V graphs given as options.
  1. (1)[figure: I-V graph, curve in first quadrant rising sharply after a small threshold voltage]
  2. (2)[figure: I-V graph with axes crossing, curve in the fourth quadrant (V positive, I negative) bending from the I axis down to the V axis]Official answer
  3. (3)[figure: I-V graph, straight line through the origin in the first quadrant]
  4. (4)[figure: I-V graph with axes crossing, flat near origin, rising steeply for positive V and falling steeply for negative V]

Question text from the official JEE Main paper published by NTA; answer from the final answer key. Chapter, topic and idea tags, difficulty and skill are Lumi’s. This question needs a figure we do not reproduce; it is described in words above. Lumi analyses 108 of the 174 JEE Main shifts held from 2017 to 2026.
