Experimental determination of the light-trapping-induced absorption enhancement factor in DSSC photoanodes

Beilstein Journal of Nanotechnology, 2015
For dye-sensitized solar cells (DSSC), the fundamental process that determines the maximum short-circuit current is the absorption of light. In such devices, this is produced by the concurrent phenomena of light absorption by dye molecules and light ...

Enhancing Charge Transport and Extraction in Ta3N5 Photoanodes Via Ti Doping and TiN Contact Layers

Small, EarlyView.
Ta3N5${\rm Ta}_3{\rm N}_{5}$ is a promising photoanode for solar water splitting but suffers from poor charge transport and interfacial losses. We combine Ti compensation doping with ultrathin TiN back‐contact interlayers to suppress bulk recombination, enhance carrier mobility and lifetime, and enable efficient carrier extraction, yielding ...

Direct Synthesis of Exfoliated Carbon Nitride Mediated by Sodiated Cellulose Nanocrystals for Photocatalytic and Adsorbent Applications

Small, EarlyView.
Few atomic‐layer‐thick carbon nitride nanosheets (CNNS) were synthesized using an in situ exfoliation technique. The directly exfoliated CNNS exhibited a wider electronic bandgap along with a fourfold increase in specific surface area and tenfold increase in pore volume.

Selective Solar CO2 Conversion into Ethanol Using Atomic‐Scale Copper Clusters Anchored π‐extended Poly(heptazine imide)

Small, EarlyView.
Atomic‐scale copper clusters anchored on π‐extended poly(heptazine imide) enable selective, sacrificial‐agent‐free solar conversion of carbon dioxide (CO2) to ethanol. The catalyst promotes interfacial charge separation and stabilizes key carbon‐carbon coupling intermediates, providing a molecularly defined platform for direct C2 fuel synthesis under ...
