The backreaction in dye-sensitized solar cells (DSSCs) was long ago recognized as one of the main causes of decreasing energy conversion efficiency. Hence, many different approaches have been attempted to reduce the backreaction. In the present work,

Several copper chalcogenide nanoparticles have been investigated as attractive candidates for replacing toxic (lead and cadmium based) and expensive (indium based) semiconductors. Among these materials, copper antimony sulfides present promising phys

Application of photocatalysts that strongly absorb within the visible range is a common strategy to improve the efficiency of photoelectrochemical (PEC) systems; this may translate to high photocurrents, but it is not always the case. Here, we show t

Generally, anatase is the most desirable TiO2 polymorphic phase for photovoltaic and photocatalytic applications due to its higher photoconductivity and lower recombination rates compared to the rutile phase. However, in applications where temperatur

Atomically-dispersed metal catalysts (ADMCs) on surfaces have demonstrated high activity and selectivity in many catalytic reactions. However, dispersing and stabilising individual atoms in support materials in an atom/energy-efficient scalable way s

The development of efficient advanced functional materials is highly dependent on properties such as morphology, crystallinity, and surface functionality. In this work, hierarchical flowerlike nanostructures of SrTiO3 have been synthesized by a simpl
