Fabrication and characteristics of ZnO/OAD-InN/PbPc hybrid solar cells prepared by oblique-angle deposition.

In this work, lead phthalocyanine (PbPc) and ZnO/InN inorganic semiconductor films prepared by oblique-angle deposition (OAD) were layered to form heterojunction organic/inorganic hybrid photovoltaic solar cells. Among the available organic materials, phthalocyanines, particularly the non-planar ones such as PbPc, are notable for their absorption in the visible and near infrared regions. The organic/inorganic hybrid solar cells fabricated on ZnO/OAD-InN/PbPc showed short-circuit current density (J(SC)), open-circuit voltage (V(OC)), and power conversion efficiencies (η) of 1.2 mA/cm², 0.6 V and 0.144%, respectively.
