Spectral Features of Zinc Phthalocyanine: Optics, Stark Spectroscopy, and Photovoltaics

Abstract

The results of spectral analysis of organic semiconductor, zinc phthalocyanine (ZnPc), which is one of the best donor materials for solar power engineering but is relatively rarely used in practice, are reported. The study of the ZnPc spectral features was performed in three different directions: optical measurements of the absorption spectra of thin films, Stark spectroscopy with information about dipole moments and polarizabilities of molecules in the solid phase, and investigation of the photovoltaic effect in simple ZnPc-based heterostructure with variation in the active-layer thickness.
