Robust Cuprous Phenanthroline Sensitizer for Solar Hydrogen Photocatalysis

Hydrogen producing water treatment through solar photocatalysis†

Hydrogen is being intensively investigated as a new energy carrier that stores and transports energy obtained from renewable energy resources (e.g., solar and wind power) to the point of use. In particular, efficient methods that can convert solar energy into hydrogen are being actively sought. One of the ideal methods is solar hydrogen production from water splitting that can be driven by phot...

Dark Photocatalysis: Storage of Solar Energy in Carbon Nitride for Time-Delayed Hydrogen Generation.

While natural photosynthesis serves as the model system for efficient charge separation and decoupling of redox reactions, bio-inspired artificial systems typically lack applicability owing to synthetic challenges and structural complexity. We present herein a simple and inexpensive system that, under solar irradiation, forms highly reductive radicals in the presence of an electron donor, with ...

Solar synthesis: prospects in visible light photocatalysis.

Chemists have long aspired to synthesize molecules the way that plants do-using sunlight to facilitate the construction of complex molecular architectures. Nevertheless, the use of visible light in photochemical synthesis is fundamentally challenging because organic molecules tend not to interact with the wavelengths of visible light that are most strongly emitted in the solar spectrum. Recent ...

An improved perylene sensitizer for solar cell applications.

A highly efficient organic sensitizer for dye-sensitized solar cells.

We have synthesized a highly efficient organic dye for a dye-sensitized solar cell; the overall solar-to-energy conversion efficiency was 9.1% at AM 1.5 illumination (100 mW cm(-2)): short-circuit current density (J(sc)) = 18.1 mA cm(-2), open circuit photovoltage (V(oc)) = 743 mV and fill factor (ff) = 0.675.
