Achieving high current densities without thermal performance degradation at high temperatures is one of the main challenges for enhancing the competitiveness of photo-electrochemical energy storage systems. We describe a system that overcomes this challenge by incorporating an integrated photoelectrode with a redox flow cell, which functions...

MoOX is commonly considered to be a high work-function semiconductor. From x-ray photoelectron spectroscopy and photoelectrochemical analysis, it is shown that MoOX can be considered as an effective hole transfer layer for the GaP-based device. Specifically, in the absence of carbon contamination using an ion beam cleaning step, the oxygen...

Scale-up to large-area Cu(In, Ga)Se <sub>2</sub> (CIGS) solar panels is proving to be much more complicated than expected. Particularly, the non-vacuum wet-chemical buffer layer formation step has remained a challenge and has acted as a bottleneck in industrial implementations for mass-production. This technical note deals with the...

We introduce the synthesis of hybrid nanostructures comprised of ZnOnanocrystals (NCs) decorating nanosheets and nanowires (NWs) of MoS2prepared byatomic layer deposition (ALD). The concentration, size, and surface-to-volume ratio ofthe ZnO NCs can be systematically engineered by controlling both the number of ZnOALD cycles and the properties of...

Recent advances in photoelectrochemical redox flow cells, such as solar redox flow batteries, have received much attention as an alternative integrated technology for simultaneous conversion and storage of solar energy. Theoretically, it has been reported that even single- photon devices can demonstrate unbiased photo-charging with high solar-to...

In recent years, solar redox flow batteries have attracted attention as a possible integrated technology for simultaneous conversion and storage of solar energy. Unlike solar water splitting technologies which require at least 1.8V for meaningful performance, a lesson learned from previous solar redox flow battery (SRFB) studies is that even...

This work investigates long-term photoelectrochemical hydrogen evolution (82 days) in 1 M HClO4 using a TiO2:H protected crystalline Si-based photocathode with metal-oxide-semiconductor (MOS) junctions. It is shown that day/night cycling leads to relatively rapid performance degradation while the photocurrent under the continuous light condition...

In recent years, research in solar energy storage with photoelectrochemical cells (i.e., solar redox flow batteries: SRFBs) has resurged. This development is emerging in parallel with the growing field of research into organic redox couples intended for aqueous redox flow batteries (RFBs) in a range of different pH environments. In a solar...
