In this webinar, Dr. Huang discusses Bruker's open-architecture AFM platform and its flexibility for complicated application needs such as those inherent in solar fuel research. Prof. Fan then demonstrates his development of spatially-resolved surface photovoltage (SPV) microscopy, used to image surface photo-induced charge transfer dynamics. Such results can provide guidelines for designing efficient solar fuel-generating devices.
This joint webinar includes two parts:
In the first part of this webinar, Dr. Teddy Huang (Bruker) reviews recent AFM applications for solar fuels research (converting sunlight, water, and carbon dioxide into hydrogen and liquid fuels). He details challenges resulting from the complexity of materials/device characterization and limitations of general small-sample AFMs, then introduces the recent progress towards solutions for energy research.
In the second part of the webinar, Prof. Fengtao Fan (Chinese Academy of Science) introduces spatially-resolved surface photovoltage (SPV) microscopy, a five-year technical and applications development in his lab based on a Bruker Dimension Icon AFM. This KPFM-based SPV technique has been used for imaging the transfer dynamics of photocarriers generated by absorbing sunlight, providing fundamental insights and practical guidelines for device designs. Prof Fan will take the popular semiconductor metal oxide photoanodes BiVO4 and TiO2 as examples to demonstrate recent important applications of the SPV microscopic technique in advancing solar fuels research.
