Photoelectrochemistry is a subfield of study within physical chemistry concerned with the interaction of light with electrochemical systems.
The interest in this domain is high in the context of development of renewable energy conversion and storage technology.
Because fossil fuels are non-renewable, it is necessary to develop processes to obtain renewable resources and use clean energy.
Artificial photosynthesis, photoelectrochemical water splitting and regenerative solar cells are of special interest in this context.

Very recently scalable all-perovskite based PEC photoelectrochemical system as solar hydrogen panel has been developed with >123 cm2 area.
[3] Photoelectrochemistry has been intensively studied in the field of hydrogen production from water and solar energy.
Recently many materials have shown promising properties to split efficiently water but TiO2 remains cheap, abundant, stable against photo-corrosion.
Currently Quantum Dots sensitization is very promising but more research is needed to find new materials able to absorb the light efficiently.
The depletion of fossil fuels encourages scientists to find alternatives to produce hydrocarbon compounds.
