Boosting the Open Circuit Voltage and Fill Factor of QDSSCs Using Hierarchically Assembled ITO@Cu2S Nanowire Array Counter Electrodes.
H hierarchically assembled ITO@Cu2S nanowire arrays with conductive single-crystalline ITO cores and Cu2Snanocrystal shells were designed as efficient QDSSCs CEs, which exhibited an unprecedentedly high Voc and shunt resistance. Expand
Self-powered and broadband lead-free inorganic perovskite photodetector with high stability.
This work developed for the first time full inorganic Cs3Bi2I9-xBrx perovskites based photodetectors and modulate their performance by varying x in composition systematically and can maintain over 96% of the initial value after 100 days owing to the high stability of the core perovkite film. Expand
ITO@Cu2S tunnel junction nanowire arrays as efficient counter electrode for quantum-dot-sensitized solar cells.
The high-quality tunnel junctions formed between n-type ITO nanowires and p-type Cu2S nanocrystals led to the considerable decrease in sheet resistance and charge transfer resistance and thus facilitated the electron transport during the operation of QDSSCs. Expand
In situ nitrogen-doped nanoporous carbon nanocables as an efficient metal-free catalyst for oxygen reduction reaction
A new N-doped carbon nanomaterial with nanoporous coaxial nanocable structure was designed for achieving the requirements of high nitrogen content, proper nitrogen bonding state, and sufficientExpand
Physical vapor deposition of amorphous MoS2 nanosheet arrays on carbon cloth for highly reproducible large-area electrocatalysts for the hydrogen evolution reaction
Molybdenum sulfide materials have been shown to be promising non-precious metal catalysts for the hydrogen evolution reaction (HER). This work reports a facile and scalable preparation method forExpand
Solvent-induced oriented attachment growth of air-stable phase-pure pyrite FeS2 nanocrystals.
It was found that the solvents could control the OA process and thus the morphologies of the products, and 1-octanol contributed to the long-term stability of these pyrite nanomaterials. Expand
Engineering the interfaces of ITO@Cu2S nanowire arrays toward efficient and stable counter electrodes for quantum-dot-sensitized solar cells.
ITO@Cu2S core-shell nanowire arrays were developed to fabricate CEs for QDSSCs, which provided more active catalytic sites and easy accessibility for electrolyte due to the three-dimensional structure upon use as CEs and exhibited excellent and thickness-dependent performance. Expand
Alloy-induced phase transition and enhanced photovoltaic performance: the case of Cs3Bi2I9−xBrx perovskite solar cells
Cs3Bi2I9 is a promising inorganic, nontoxic, and stable perovskite material for solar cell applications, but the power conversion efficiency of Cs3Bi2I9-based solar cells is relatively low becauseExpand
Highly efficient and stable FASnI3 perovskite solar cells with effective interface modulation by PEABr treated low-dimensional perovskite layer.
This work definitely deepens the understanding to the suppression effect of PEABr on the oxidation of Sn2+ and paves a new way to fabricate promising tin halide PSCs by facile interface engineering. Expand
