A scanning probe microscopy study of nanostructured TiO2/poly(3-hexylthiophene) hybrid heterojunctions for photovoltaic applications

Beilstein Journal of Nanotechnology, 2018
The nanoscale morphology of photoactive hybrid heterojunctions plays a key role in the performances of hybrid solar cells. In this work, the heterojunctions consist of a nanocolumnar TiO2 surface covalently grafted with a monolayer of poly(3 ...

Defect‐Engineered MOF/COF S‐Scheme Heterojunction With Dual‐Channel Charge Transport for Ultraefficient Solar‐Powered Heavy Metal Remediation

Advanced Science, EarlyView.
Covalent bond MOF/COF S‐scheme which generated via vacuum‐induced oxygen vacancies are report. OVs at the interface can trigger a dual‐channel charge transport mechanism, significantly enhancing catalytic performance. This work not only designs a high‐performance photocatalysts for environmental remediation, but also induces a new concept of “defect ...

Integrated Bulk–Surface Engineering Stabilizes MA‐Free Wide‐Bandgap Perovskites for Tandem Photovoltaics

Advanced Science, EarlyView.
High‐bromide wide‐bandgap perovskites suffer from defects and phase segregation, limiting tandem performance. We report a bulk–surface coupling effect to heal lattice/surface defects and suppress halide migration. As a result, the wide‐bandgap device achieves 23.71% efficiency, while monolithic Si‐based tandems reach 32.26%, exhibiting exceptional long‐

Electronic Modulation of K⁺‐Intercalated Polymeric Carbon Nitride via ─C≡N/─OH Functionalization for Efficient Photocatalytic H2O2 Production

Advanced Science, EarlyView.
K+ is successfully embedded in the PCN interlayers via a high‐temperature polymerization. The incorporation of K+ perturbs the local electronic structure via interaction with nitrogen lone pairs, narrowing the PCN bandgap, which exhibits superior photocatalytic performance, achieving a high H2O2 generation rate both in situ and under sunlight ...

Smart Energy–Harvesting Coating for Moisture–Droplets Based on Ionic Diodes and Transistor–Like Structures

Advanced Science, EarlyView.
A smart power‐generating coating is developed to harvest energy from both ambient humidity and impacting liquid droplets. The integrated system delivers sustained open‐circuit voltages of 0.85 V from moisture and up to 36 V from droplets. Its scalable coating architecture enables a continuous power supply for low‐power electronic devices.
