Area of Science:

  • Materials Science
  • Renewable Energy
  • Solid-State Physics

Background:

  • Inorganic perovskite solar cells (IPSCs) offer stability and tunable bandgaps (~1.7 eV) for next-generation photovoltaics.
  • IPSCs exhibit lower performance than hybrid counterparts due to interface defect states and energy level mismatches.

Purpose of the Study:

  • To enhance the efficiency of inverted inorganic perovskite solar cells (IPSCs) by addressing interface issues.
  • To investigate the role of 4-fluorobenzylamine hydrochloride (p-F-PMACl) as an interface modifier.

Main Methods:

  • Introduction of 4-fluorobenzylamine hydrochloride (p-F-PMACl) as an interfacial layer in IPSCs.
  • Analysis of defect passivation mechanisms, including iodine vacancy repair and lattice correction.
  • Optimization of energy level alignment and reduction of nonradiative recombination.

Main Results:

  • p-F-PMACl effectively passivates iodine vacancy (VI) defects and Pb-I defects through interactions of Cl and F sites with Pb.
  • Optimized energy level alignment and reduced defect density led to suppressed nonradiative recombination.
  • Achieved a champion power conversion efficiency (PCE) of ~21% with a record low open-circuit voltage (VOC) deficit of 446 mV.
  • Demonstrated 18.91% PCE for 1.77 eV bandgap IPSCs with VOC > 1.31 V.

Conclusions:

  • 4-fluorobenzylamine hydrochloride is a highly effective interface modifier for improving IPSC performance.
  • Defect passivation and energy level optimization are crucial for realizing the full potential of inorganic perovskite solar cells.
