I-15 – Photochemical and photocatalytic energy conversion



Organizers: Ian Sharp, Francesca Toma (Lawrence Berkeley National Laboratory).

Solid state photoelectrochemical and photocatalytic systems offer promise for direct conversion of solar energy to useful chemical products, including hydrogen and carbon-based fuels. Key components of these systems include semiconductor light absorbers, electrocatalytic materials, and thin film interface layers. Each of these materials must be effectively coupled to promote directed charge flow and support catalytic transformations, while retaining their efficiency and stability. Active research in the field is dedicated to discovery of new light absorbers and catalysts, understanding of energy transduction mechanisms in existing and emerging systems, and controlling interactions between different materials and phases. This Symposium will cover central topics and latest advances in solid state photoelectrochemical and photocatalytic energy conversion, including advanced synthesis and characterization approaches. A focus of the Symposium will be on areas in which concepts in solid state ionics can inform mechanistic understanding and future development of functional systems. This will include phase transformations and ion intercalation in active catalysts (dark and photo); synthesis and properties of complex materials for driving (photo)electrochemical energy conversion, such as metal oxides, nitrides, and oxynitrides; defects, impurities, and polarons in light absorbers, catalysts, and corrosion protection layers; in situ and operando characterization of functional materials; photocorrosion pathways and non-equilibrium processes; and dynamics and energetics at interfaces.


Abstracts are solicited in, but not necessarily limited to, the following areas:

In this Symposium are also welcome those contributions which cover the topics beyond the above-described areas. This is done to provide the audience with a comprehensive description of Solid State Ionics. If your contribution is difficult to host within the above areas, please do not hesitate to contact directly the Conference Chairmen at ssi21@dii.unipd.it for advice.
