Enhanced Quantum Yield in Porphyrin Heterodimer Solar Cells

Abstract
The Al/porphyrin/Au sandwich-type photovoltaic cell with a heterodimer solid of 5,10,15,20-tetraphenylporphyrinatozinc (Zntpp) and 5,10,15-triphenyl-20-(3-pyridyl)porphyrin (H2pyp3p) exhibits a remarkably large photocurrent quantum yield, compared with the cell with a pure Zntpp or an H2pyp3p solid.
