Grain Boundary Engineering with Self-Assembled Porphyrin Supramolecules for Highly Efficient Large-Area Perovskite Photovoltaics

Zihan Fang et al.

Summary: Grain boundary management is crucial for the performance of polycrystalline perovskite solar cells, and a designed supramolecular binder can simultaneously passivate defects and promote carrier transport, leading to improved efficiency and stability. The NiP-doped PSCs achieved a certified efficiency of 22.1% and retained over 80% initial performance after continuous illumination or heating for 3000 hours at 85 degrees C.

Perovskite solar cells with atomically coherent interlayers on SnO2 electrodes

Hanul Min et al.

Summary: By introducing an interlayer between the electron-transporting and perovskite layers in perovskite solar cells, researchers have successfully enhanced charge extraction and transport from the perovskite, leading to higher power conversion efficiency and fewer interfacial defects. The coherent interlayer allowed the fabrication of devices with a certified efficiency of 25.5%, which maintained about 90% of its initial efficiency even after continuous light exposure for 500 hours. The findings provide guidelines for designing defect-minimizing interfaces in metal halide perovskites and electron-transporting layers.

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 perovskite-substrate interfaces for high-performance perovskite modules

Shangshang Chen et al.

Summary: The study found that DMSO liquid additive trapped in perovskite-substrate interfaces during film formation led to voids, accelerating film degradation. Partial replacement of DMSO with solid-state carbohydrazide reduced interfacial voids and increased stability. Blade-coated p-i-n structure PSCs achieved a maximum PCE of 23.6% without efficiency loss after stability tests, demonstrating improved efficiency and stability with the new approach.
