Spectral Absorption Study in OPV Device

Dr. Hemant Kumar

Government Degree College, Kasganj, UP, India.


We have studied the UV-Visible absorption spectrum of copper phthalocyanine (CuPc), zinc phthalocyanine (ZnPc) and Metal free phthalocyanine (Hydrogen Phthalocyanine – H2Pc). We also study the effect of CuPc, ZuPc and H2Pc as donar layer in (CuPc)/ fullerene (C60), (ZuPc)/ (C60) and (H2Pc)/ (C60) bilayer organic photovoltaic device (OPV) or Organic Solar Cell (OSCs), the enhancement of the overall performance of the OSCs with better spectral absorption. A variation in Efficiency in the device architecture has been observed. The variation in η is dominantly attributed to the increment in short circuit current density (Jsc) due to efficient photon harvesting by donor.

Keywords: Phthylocyanine, Bilayer OPV, UV-Visible spectrum.
