Broad‐Spectral Response Lead Halide Perovskite Solar Cells Through Integration of Multifunctional Organic Bulk‐Heterojunction and Quantum‐Cutting Downconversion Materials

Rare Metals, EarlyView.
ABSTRACT Expanding near‐infrared (NIR) spectral response and utilizing ultraviolet (UV) photons are effective strategies for enhancing the power conversion efficiency (PCE) of lead halide perovskite solar cells (PSCs). However, the range of NIR spectral response extension and the utilization of UV light for devices are not enough, and the loss of ...

Triggering and Preventing Cyclization of o-Amino-Guanidinobenzenes to 2-Amino-Benzimidazoles. [PDF]

Chemistry
o‐Amino‐guanidinobenzenes are generally prone to cyclization to 2‐amino‐benzimidazoles. In this work, strategies to prevent such cyclizations are developed, allowing to use these compounds as ligands in coordination chemistry and for the design of novel (unsymmetrical) redox‐active ligands.

Recent Advances in Chemical Bath Deposition of Electron and Hole Transport Layers for Perovskite Solar Cells and Modules

Rare Metals, EarlyView.
ABSTRACT The development of high‐efficiency, stable, and scalable perovskite solar cells/perovskite solar modules (PSCs/PSMs) highly depends on the performance and cost‐effectiveness of functional layers such as electron transport layers (ETLs) and hole transport layers (HTLs).

Anion Component Engineering of Spontaneous Perovskite Passivators for Energy Alignment Modulations in Perovskite Solar Cells

Small, EarlyView.
n‐Octylammonium bis(fluorosulfonyl)imides (OA‐FSI, OA‐TFSI, and OA‐PFSI), used as additives for spiro‐OMeTAD hole‐transport materials (HTMs) in perovskite solar cells (PSCs), allow spontaneous perovskite passivation during HTM deposition. Anion component engineering of the OA‐bis(fluorosulfonyl)imides effectively modulate energy alignment in PSCs via ...

Functional polymer materials containing heavy group‐14 elements focusing on germanium and tin

Smart Molecules, EarlyView.
The synthesis, functions, and applications of the polymers containing heavy group 14 elements focusing on germanium and tin are outlined. Owing to their large atomic radii and weak binding energies, the polymers show unique properties: chromism, luminescence, carrier mobility, and reactivity to produce radials and higher coordinated states.

Assessing Proton Radiation Hardness of Antimony Chalcogenide Solar Cells

Solar RRL, EarlyView.
This paper discusses the effect of proton radiation on the device performance of antimony chalcogenide solar cells. Sb2S3 and Sb2(S, Se)3 solar cells are exposed to two different proton energies (100 and 300 keV) with fluences ranging from 1011 to 1014 protons/cm2.
