Statement 1 Correct: 
  • Perovskites are a class of materials that share a similar structure and display a myriad of exciting properties like superconductivity, magnetoresistance, etc. Solar cells are currently the most prominent perovskite application, as synthetic perovskites are recognized as potential inexpensive base materials for high-efficiency commercial photovoltaics.
Statement 2 Incorrect:
  • They are known for their exceptional optical properties. They can efficiently absorb and emit light across a wide range of wavelengths, from visible to near-infrared. This property has made them a promising candidate for solar cells and light-emitting devices.

Explanation:

Statement 1:
- Perovskite materials have gained significant attention in the field of photovoltaics due to their potential as inexpensive base materials for high-efficiency commercial solar cells.
- The unique properties of perovskite materials, such as high absorption coefficients and long carrier diffusion lengths, make them ideal candidates for photovoltaic applications.

Statement 2:
- Perovskite materials have demonstrated the ability to efficiently absorb and emit light across a wide range of wavelengths, from visible to ultraviolet.
- This broad spectral response of perovskite materials makes them promising for use in solar cells that can harvest a larger portion of the solar spectrum.

Conclusion:
- While Statement 1 is correct in highlighting the potential of perovskite materials for high-efficiency commercial photovoltaics, Statement 2 is incorrect as it provides an accurate description of the optical properties of perovskite materials.
