Excitonic Solar Cells Using 2D Perovskite of (BA)2(FA)2Pb3I10

Shu Hu et al.

Summary: This study fabricated two-dimensional (2D) perovskite films and solar cells using mixed BA and FA cations at different concentrations and temperatures, with the addition of thiourea in the precursor solution. While the 1.0 M solution resulted in larger crystalline grain size, devices from the 0.25 M solution using the hot-cast technique showed better performance on average. Spectra analysis showed exciton absorption in devices from the 0.25 M solution, which was lacking in devices from the 1.0 M solution.

Revealing Charge Carrier Mobility and Defect Densities in Metal Halide Perovskites via Space-Charge-Limited Current Measurements

Vincent M. Le Corre et al.

Summary: Space-charge-limited current (SCLC) measurements are widely used to study charge carrier mobility and trap density in semiconductors, but their application to metal halide perovskites is complicated by the mixed ionic and electronic nature of these materials. The presence of mobile ions strongly affects the measurements, requiring a refined analysis and interpretation of SCLC. Pulsed SCLC, combined with drift-diffusion simulations, offers a reliable method for simultaneously extracting mobility, trap, and ion densities in perovskite semiconductors.

Film Formation Control for High Performance Dion-Jacobson 2D Perovskite Solar Cells

Xu Zhang et al.

Summary: In this study, a detailed investigation into the effects of different solution-casting processes on film formation for DJ perovskite semiconductors was conducted. It was found that faster solvent removal through hot-casting or antisolvent dripping resulted in a more uniform thickness distribution of quantum wells, leading to enhanced carrier transport and increased power conversion efficiencies for photovoltaic devices. High efficiency of 15.81% was achieved for hot-casting devices, marking it as the highest efficiency for aromatic spacer-based DJ perovskite solar cells.

Lewis Base Passivation of Quasi-2D Ruddlesden-Popper Perovskite for Order of Magnitude Photoluminescence Enhancement and Improved Stability

Yukta et al.

Summary: This study demonstrates a significant enhancement in optical properties of passivated quasi-2D perovskites, confirming complexation of passivating molecules with the surface and nanocrystal pinning phenomena. Passivation resulted in reduced crystal grain size, enhanced fluorescence intensity, improved average lifetime, and deactivation of acceptor-type defects using Lewis bases. Contact angle measurements confirmed the enhanced stability of passivated films, suggesting a viable strategy for improving photoluminescence in quasi-2D perovskite films.
