Intact 2D/3D halide junction perovskite solar cells via solid-phase in-plane growth

Yeoun-Woo Jang et al.

Summary: Researchers have developed a solid-phase method to grow phase-pure two-dimensional perovskites in perovskite solar cells, enhancing device efficiency and stability. By growing a stable two-dimensional film on top of a three-dimensional film using a solvent-free method, an intact 2D/3D heterojunction is formed, resulting in high photovoltage in the device.

Dual Additive for Simultaneous Improvement of Photovoltaic Performance and Stability of Perovskite Solar Cell

In Seok Yang et al.

Summary: Additive engineering is an efficient approach for improving photovoltaic performance and phase stability of formamidinium-based perovskite, with a dual additive strategy of mixing MACl and CsCl proving successful in enhancing open-circuit voltage Voc, reducing trap density, and increasing resistance against charge recombination. The best power conversion efficiency achieved with the dual additive is 23.22%, outperforming single additive strategies using MACl or CsCl.

Unusual Hole Transfer Dynamics of the NiO Layer in Methylammonium Lead Tri-iodide Absorber Solar Cells

Hyunwoo Yang et al.

Summary: In this study, nickel oxides (NiO) were deposited as hole transport layers (HTLs) in perovskite solar cells (PSCs) with controlled thickness by atomic layer deposition (ALD). Ultrafast transient absorption spectroscopy (TAS) showed ground state bleaching (GSB) recovery, indicating backward hole injection between perovskites and NiO HTLs due to their similar valence band (VB) energy positions. The thickness increase of NiO HTLs induced a red-shift in the photoinduced hole absorption spectrum and a decrease in photoluminescence intensity in near-infrared (NIR) femtosecond TAS.

Efficient perovskite solar cells via improved carrier management

Jason J. Yoo et al.

Summary: Metal halide perovskite solar cells have shown great potential to disrupt the silicon solar cell market with their improved performance, yet still face limitations in light-harvesting due to charge carrier recombination. Efforts to enhance charge carrier management offer a path to increase device performance and approach the theoretical efficiency limit of PSCs.

Stabilizing Mixed Halide Lead Perovskites against Photoinduced Phase Segregation by A-Site Cation Alloying

Pronoy Nandi et al.

Summary: The research demonstrates that substituting methylammonium (MA(+)) ions into mixed halide perovskites can suppress photoinduced phase segregation, with significant suppression observed at 10% substitution. The activation energy for photoinduced phase segregation is increased by introducing 10% MA(+) into the perovskite, indicating an increased energetic barrier for halide segregation. The study also shows the effect of A-site cation alloying against photoinduced phase segregation in active devices such as phototransistors and photovoltaic cells.
