Abstract
Electric and photovoltaic characteristics of an orgainic p-n junction photovoltaic cell are described, where the p-type and n-type compounds used are phthalocyaninatozinc (II) (ZnPc) and 5, 10, 15, 20 -tetra (3-pyridyl) porphyrin (TPyP), respectively. The p-n junction cell with a thin film of TPyP exhibited stronger spectral sensitization and better spectral match to a solar spectrum than the Schottky barrier cells using either TPyP and ZnPc. The energy conversion efficiency found was about 2% for monochromatic light at 430 nm.
