Efficient defect-passivation and charge-transfer with interfacial organophosphorus ligand modification for enhanced performance of perovskite solar cells

Solar Energy Materials and Solar Cells, 2020
Interfacial engineering is an effective method to improve the performance of perovskite solar cells. Nevertheless, it is still challenging to find a material as interfacial layer with the dual function of defect-passivation and efficient charge-transfer.

Organophosphorus Insecticide Toxicity

JAMA: The Journal of the American Medical Association, 1965
To the Editor:— In the April 12, 1965 issue ofThe Journal( 192 : 178-179) there appears an answer by Joseph H. Holmes, MD, to a question concerning the prevention of poisoning by organophosphorus insecticides such as parathion and malathion. Some 50 organic compounds of phosphorus have been registered as insecticides by the US Department of ...
