Air-Degradation Mechanisms in Mixed Lead-Tin Halide Perovskites for Solar Cells

Vincent J-Y Lim et al.

Summary: Mixed lead-tin halide perovskites are suitable for the bottom subcell of all-perovskite tandem photovoltaic devices due to the bandgap-bowing effect. However, these materials degrade in ambient air, which negatively impacts their optoelectronic properties. This study unravels the degradation mechanisms of APb(x)Sn(1-x)I(3) perovskites and highlights the need for passivation strategies tailored specifically to mixed lead-tin iodide perovskites.

Relationship between Carrier Density and Precursor Solution Stirring for Lead-Free Tin Halide Perovskite Solar Cells Performance

Ajay Kumar Baranwal et al.

Summary: The oxidation process of tin halide perovskite precursor (THP) with dimethyl sulfoxide (DMSO) as the solvent has interesting drawbacks. Adding GeI2 can hinder THP oxidation under progressive stirring. The stirring time of the precursor solution affects the carrier density and semiconducting properties of the fabricated films, as DMSO increases the oxidation-induced carrier density. On the other hand, dimethylformamide (DMF) suppresses the oxidation-induced carrier density. After 24 hours, an efficiency of 10.26% is achieved with DMF as the stirring solvent, while 7.12% is achieved with DMSO.

Effect of binary additives in mixed 2D/3D Sn-based perovskite solar cells

Sanjay Sandhu et al.

Summary: The optimal blend of 8 mol% PEAI and 1 mol% EDAI(2) produces a pinhole-free, compact perovskite film with enhanced crystallinity, preferred orientation, low background charge carrier density, reduced trap states, and suppressed recombination losses. This combination improves interlayer coupling for better charge transfer at interfaces, leading to a record power conversion efficiency of 8.47% and enhanced stability of up to 5 days in ambient conditions without additional encapsulation.

Spacer Cation Tuning Enables Vertically Oriented and Graded Quasi-2D Perovskites for Efficient Solar Cells

Ze Wang et al.

Summary: Halide substitution in phenethylammonium spacer cations is an effective strategy to enhance the performance of PEA based perovskite solar cells. The substitution eliminates the n = 1 2D perovskite phase, leading to perpendicular crystal orientation and orderly distribution of different n-phases in the films. This results in significantly improved power conversion efficiency and stability in the PSCs.
