NEW TRIPHENYLAMINE DERIVATIVE FOR IMPROVING ENERGY CONVERSION EFFICIENCY AND DYE-SENSITIZED SOLAR CELL COMPRISING THE SAME

摘要

PURPOSE: A novel triphenylamine derivative and a dye sensitized solar cell containing the same are provided to enhance short circuit photocurrent density. CONSTITUTION: A triphenylamine derivative is denoted by chemical formula 1. In chemical formula 1, acceptors are same or different 5-oxo-1-phenyl-2-pyrazoline-3-carboxylic acid, 2-(4-oxo-2-thioxothiazolidine-3-yl)acetic acid or (Z)-2-cyanobut-2-enoic acid. Organic dye for dye sensitized solar cells contains triphenyl amine derivative of chemical formula 1. The dye sensitized solar cell contains nanocrystalline metal oxide containing the triphenyl amine derivative of chemical formula 1, anode, electrolyte, and opposite electrode.
