Zinc phthalocyanine (ZnPc) is a promising candidate for solar-cell applications, because it is easily synthesized and is non-toxic to the environment. Recently, phthalocyanine (Pc) was considered by many researchers as the active part in all-organic solar cells, i.e. plastic solar cells. It is a self-assembling liquid crystal developed from a common deep-blue-green pigment. It exhibits a characteristic...
The devices investigated in this work consisted of an indium tin oxide (ITO)-coated glass substrate, phthalocyanine (Pc) layer and an aluminum electrode. The Schottky cell exhibits optimal performance with one ohmic and one barrier contact. The work function of the ITO film is typically around 4.5–4.8 eV, while the HOMO level of phthalocyanine films is typically around 5.2 eV. It is known that surface...
