Rare earth bisphthalocyanine complexes, p-type organic compounds, have been
used in Schottky and pn photovoltaic cells.; Depending on the lanthanide r
are earth of Pc(2)Ln complex, the absorption band characteristics of Pc and
Pc(2)Ln generates intense, weak or no photocurrent. This observation can b
e directly related to the size of the Ln or to the structural organisation
of the Pc(2)Ln thin films.
