Boron sub-2,3-naphthalocyanine chloride Chemical Properties,Usage,Production

Description

Due to its thermal stability, boron sub-2,3- naphthalocyanine chloride (SubNc) has been studied as a photoactive material for PV cells. In addition, a SubNc film exhibits strong absorption in the red light region. SubNc had been investigated as a potential red-sensitive organic photoconductive film (OPF). A photoconductive cell was fabricated, and its current-voltage characteristics, both with and without light irradiation, and external quantum efficiency (EQE) were determined. SubNc film absorbed light in the red region well, with an absorption peak at 695 nm. The EQE of the cell reached 80% when the applied bias was 15 V. In addition, the blocking layers effectively suppressed dark current in the OPF, corresponding to a current density of 20 nA/cm2 at 15 V. These results indicate that SubNc is a promising candidate as a red-sensitive OPF[1].
