Illumination‐Dependent Interfacial Recombination in Perovskite Photovoltaics Driven by Trap States in Metal Oxide Electron Transport Layers

open access: yesAdvanced Science, EarlyView.
Changes in light intensity impact trap states introduced at the metal oxide/perovskite interface. Comparing SnO2, TiO2 and ZnO electron transport layers reveals high interfacial trapping and recombination under high‐light, while bulk defects become more dominant under low‐light.

Molecular Engineering of Multi‐Site Small‐Molecule Chelation for Highly Efficient and Stable n‐i‐p Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
Li+ ion migration in Li‐TFSI‐doped Spiro‐OMeTAD impairs efficiency and device stability. Rather than replacing Li+, a multi‐site chelator is designed and introduced into Spiro‐OMeTAD to immobilize Li+ ions with high affinity. The synergistic effects of suppressing ion migration, inducing ordered molecular packing, boosting p‐doping efficiency, and ...

From Laboratory to Industry: Evaporating Functional Layers at High Rates for Fully Textured Perovskite/Silicon Tandems

open access: yesAdvanced Energy Materials, EarlyView.
Perovskite/silicon tandem solar cells exhibit outstanding efficiencies; however, the development of scalable and high‐throughput manufacturing processes remains a critical challenge. Here, we demonstrate accelerated deposition of multiple functional layers via high‐rate thermal evaporation without compromising film quality or device performance.

Nickel‐Free Perovskite Solar Cells Enabled by Self‐Assembled Monolayers: A Pathway to Efficient and Recyclable Devices

open access: yesAdvanced Energy Materials, EarlyView.
Replacing toxic NiOx with phenyl‐substituted phosphonic‐acid carbazole monolayers (Ph‐5PACz) yields inverted perovskite solar cells that are efficient and recyclable. The nickel‐free interface reaches 25.3% efficiency and enables closed‐loop ITO recovery with near‐98% performance retention, while life‐cycle and techno‐economic analyses confirm lower ...

Using MIS Thermally Stimulated Currents for Degradation Dependent Energetic Landscape Evaluation in Triple Cation Mixed Halide Perovskites

open access: yesAdvanced Energy Materials, EarlyView.
A state‐of‐the‐art triple cation mixed halide perovskite is characterized using thermally stimulated currents in a MIS device architecture. This enables the separate detection of densities of electron and hole states and their activation energies on the same device, unveiling defect state evolution under the degrading influence of ambient conditions ...
