Article Synopsis
  • * Researchers developed new HTMs using triphenylamine-carbazole with modifications that enhance energy level compatibility with perovskite, leading to better charge extraction.
  • * The optimized HTMs featuring halogen atoms not only passivate defects to reduce nonradiative recombination but also promote high-quality vertically oriented perovskite crystals, achieving a power conversion efficiency of 21.07% with excellent stability.

All-inorganic wide-bandgap perovskite CsPbIBr has attracted much attention because of its inherent thermal stability and ideal bandgap for the front subcell of tandem solar cells (TSCs). However, the low power conversion efficiency (PCE) and poor moisture stability of CsPbIBr still restrict its future commercialization. Herein, zirconium tetrachloride (ZrCl) was doped into CsPbIBr films to modulate the crystal growth and improve the film quality.

Owing to their insufficient light absorption and charge transport, 2D Ruddlesden-Popper (RP) perovskites show relatively low efficiency. In this work, methylammonium (MA), formamidinum (FA), and FA/MA mixed 2D perovskite solar cells (PSCs) are fabricated. Incorporating FA cations extends the absorption range and enhances the light absorption.
