Molecularly Engineered Triphenylamino-Thienyl Substituted Zinc Phthalocyanine as Dopant Free Hole Transporting Materials in Perovskite Solar Cells

Abstract

To endure the success of perovskite solar cells (PSCs), developing dopant-free hole transporting materials is of paramount importance to induce long-term stability. Phthalocyanine has emerged as a viable alternative for common Spiro-OMeTAD, due to their excellent optoelectrical properties and chemical stability. We report the design and semiconducting properties of a thienyl-triphenylamine tetrasubstituted Zinc (II) phthalocyanine, and its application into PSCs. The PSCs fabricated with Zinc phthalocyanine without the use of any dopant and additives gave a competitive power conversion efficiency in excess of 14.5%, along with long-term stability.
