Progress in Photovoltaics: Research and Applications, EarlyView.For the first time, a perovskite/perovskite/silicon triple‐junction solar cell incorporating an evaporation‐deposited inorganic CsPbI₂Br perovskite top‐cell absorber was developed. The device achieved an efficiency of 22%, an open‐circuit voltage of ~2.9 V, and a short‐circuit current of ~10 mA/cm2 over a 1‐cm2 active area.

The Formation and Transformation of Low‐Dimensional Carbon Nanomaterials by Electron Irradiation
Small, EarlyView.The article reviews irradiation phenomena in graphene‐ or graphite‐based nanomaterials from the scale of single atoms to tens or hundreds of nanometers. Observations dating back to the 1990s can now be explained on the basis of new results. The evolution of the understanding during three decades of research is presented, and the remaining problems are ...

Monolithic Perovskite/Silicon Tandem Solar Cells Enabled by Multifunctional TiOx Interconnects
Small, EarlyView.TiOx nanolayer enables a series interconnection of a perovskite top cell with a silicon wafer directly in perovskite/silicon tandem solar cells. The TiOx serves as an all‐in‐one interconnect, providing surface passivation, hole transport, and recombination junction.

Small, EarlyView.A comparative analysis of cis‐ and trans‐configured hydroxyl‐functionalized cyclohexylammonium chloride (ACHACl) ligands reveals distinct adsorption behaviors on [PbI6]4− octahedra during 2D/3D perovskite heterojunction formation. The cis isomer exhibits stronger surface interaction, leading to more effective defect passivation, including Pb0 ...

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.

Small Science, EarlyView.TiO2 is highly relevant in photoelectrochemistry, (photo)catalysis, and sensor applications, where high conductivity is crucial. Herein, a co‐doping strategy for TiO2 using Nb(V) and Sn(IV) is developed, enhancing electron extraction from perovskite and improving solar cell efficiency and stability.
