LIMNO develops a route for making 2D nanosheets with fewer defects

— Semiconducting 2D transition metal dichalogenide (2D-TMD) nanosheets are promising materials for ultrathin optoelectronic devices, but most scalable routes lead to defective nanosheets and disappointing performance. Now, in a new article, Rebekah Wells of the LIMNO lab and her colleagues have presented a new solution processable method which uses an electrochemical pellet intercalation (ECPI) technique to make high quality nanosheets with fewer defects and higher quantum efficiencies.

Insights towards optimizing electron injection in BHJ photoanodes

— The use of a bulk heterojunction (BHJ) of organic semiconductors to drive solar-to-fuel energy con version via photoelectrochemical water splitting is an emerging trend; however, the optimum energy levels of the donor and acceptor have not been established for photoanode operation with respect to electrolyte pH. Now in a new paper, Dr. Arvindh Sekar of the LIMNO lab at EPFL has revealed important factors that determine efficient electron injection.
