Abstract

This study evaluated the possibility of utilizing a drop-cast process for CuTsPc-based organic solar cells. CuTsPc thin films were deposited by drop-cast method on ITO substrate. The absorption spectra of these films show two well-defined absorption bands of phthalocyanine molecule, namely, the soret (B) and Q-band. The band gaps calculated from the absorption spectra is found to lie in the range of 1.55–4.04 eV. X-ray diffractogram of the films indicate their polycrystalline nature. Atomic force microscope (AFM) investigations of the films show granular grain like morphology. The data for mobility, dielectric constant, extinction coefficient and refractive index are also presented in this communication.
