Summary: The addition of CNDs into perovskite precursor solution leads to the deposition of a high-quality hybrid Cs(0.15)FA(0.85)PbI(3) thin film, which in turn improves the efficiency of the inverted planar perovskite solar cells. The results show that CNDs effectively passivate defects, reduce charge carrier recombination, and enhance device efficiency.

Summary: Organic-inorganic halide perovskite materials have received widespread attention and research due to their adjustable bandgap, high absorption coefficient, and simple preparation methods. The power conversion efficiency (PCE) of single-junction perovskite cells has significantly increased in recent years. All-perovskite tandem solar cells (all-PTSCs) utilizing bandgap complementary photovoltaic technology are considered a promising strategy to overcome the limitation of Shockley-Queisser and achieve high PCE at low cost. This brief review provides an overview of the structure, working principle, recent progress, existing problems, optimization strategies, and future development of all-PTSCs based on both 2-terminal (2-T) and 4-terminal (4-T) tandem modes.

Summary: Despite the popularity of the perovskite solar cell for its high power conversion efficiency, its further development is hindered by issues such as long-term stability, large-area fabrication, and stable module efficiency. To address these challenges, the authors achieve in situ anion-fixation and undercoordinated-Pb passivation during crystallization using an amidino-based ligand. The resulting devices demonstrate a power conversion efficiency of 25.3% with improved stability.

Summary: This study presents a facile yet effective method for achieving high-performance inorganic perovskite solar cells (PSCs) by post-modifying the perovskite surface with 2-thiophene ethylamine (TEA). The amine group from TEA interacts favorably with undercoordinated Pb2+ through Lewis acid-based coordination, while the thiophene ring with electron-rich sulfur assists this interaction as an electron donor. The synergetic interaction allows TEA to efficiently passivate perovskite film defects, reducing non-radiative charge recombination and improving charge carrier lifetime, resulting in significantly improved PSC performance and environmental stability.
