Consider the following statements regarding perovskite solar cells (PSCs): 1. They have longer lifespan than the traditional silicon-based solar cells. 2. The crystal structure of perovskite used in these cells increases their superconductivity. 3. The primary challenge in commercializing PSCs is their inability to achieve high power conversion efficiencies comparable to traditional silicon-based solar cells. Which of the statements given above are incorrect? |ForumIAS

Q. Consider the following statements regarding perovskite solar cells (PSCs):
1.They have longer lifespan than the traditional silicon-based solar cells.
2.The crystal structure of perovskite used in these cells increases their superconductivity.
3.The primary challenge in commercializing PSCs is their inability to achieve high power conversion efficiencies comparable to traditional silicon-based solar cells.
Which of the statements given above are incorrect?

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: C

Notes:

Explanation: Statements 1 and 3 are incorrect:

Statement 1 is incorrect: PSCs have shorter operational lifespans compared to traditional silicon-based solar cell.

Statement 2 is correct: They display interesting properties, due to their unique crystal make-up like superconductivity, giant magneto-resistance, and ferro-electricity- making them applicable to use in clean energy.

Statement 3 is incorrect: They are inexpensive and highly efficient as compared to the traditional silicon-based solar power cells.
