Linking in situ charge accumulation to electronic structure in doped SrTiO3 reveals design principles for hydrogen-evolving photocatalysts
Understanding the origin of unprecedented solar-to-hydrogen efficiencies in doped SrTiO3 has proved challenging. Linking in situ charge accumulation to electronic structure in this system now reveals design principles for hydrogen-evolving photocatalysts.

Excitation-wavelength-dependent small polaron trapping of photoexcited carriers in α-Fe2O3
The effect of polaron formation on photoconversion efficiency for oxide photocatalysts is not well known. Femtosecond extreme-ultraviolet measurements suggest that polaron localization is responsible for ultrafast trapping of photoexcited carriers in haematite.

Photovoltaic concepts inspired by coherence effects in photosynthetic systems
Lessons learned from coherent phenomena in biological photosynthetic systems may be useful to improve energy- and charge-transport in disordered materials. This Review describes coherence and its potential beneficial effects in photovoltaics.

Enhanced energy transport in genetically engineered excitonic networks
A super-Förster energy-transfer regime, where coherent and incoherent energy transport processes enhance the diffusion of excitons, is observed at room temperature by tuning the distance between the chromophores’ binding sites in a virus scaffold.
