Q. Consider the following statements about Perovskite Solar Cell:
1. Perovskites materials offer excellent light absorption, charge-carrier mobilities, which act as the light-harvesting active layer.
2. Perovskite materials are stable towards humidity and oxygen.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: A
Notes:

About Perovskite Solar Cell (PSC):

  • Perovskite Solar Cell (PSC) is made by a perovskite-structured compound. Perovskites materials offer excellent light absorption, charge-carrier mobilities, which act as the light-harvesting active layer.
  • PSCs have become commercially attractive because of the potential of achieving even higher efficiencies and very low production costs.
  • However, the challenge lies in its short- and long-term stability. Similarly, perovskite materials are unstable towards humidity and oxygen, which restricts their commercialization.

Present solar cell tech:

  • Currently, silicon-based inorganic solar cells are a major player in the market.
  • However, this technology requires high-temperature processing that results in the high price of solar panels. Further, the recycling of solar panels is perilous and complicated.
