Star-shaped triarylamine-based hole-transport materials in perovskite solar cells

Abstract

Two star-shaped HTMs with excellent optoelectronic, electrochemical, charge-transport and thermal properties show efficiencies of 13.32% and 11.52% in perovskite solar cells.

Review of current progress in hole-transporting materials for perovskite solar cells

“…The fabricated devices achieved PCE as high as 18.4%. Pineda et al [248] synthesized two unique stars shaped HTMs STR0 and STR1 that are based on triarylamine. In STR0, partially oxygen-bridged triphenylamine was utilized as core while in STR1, the core was triphenylamine and for side arms, para-substituted triphenylamine was employed.…”
