Alkylsilyl-substituted benzodithiophene-based small molecules as promising hole-transport materials for perovskite solar cells

Abstract

Organic semiconductor small molecules have gained significant attention as interfacial hole-transport materials (HTM) for application in perovskite solar cells (PSCs). Herein, we report the investigation of three donor-acceptor small molecules...

Conjugated small molecules based on alkylsilyl-modified triphenylamine: promising hole transport materials in perovskite photovoltaics

“…A similar tendency towards crystallization was observed in other small molecules, including those where terminal thiophene rings were functionalized with tributylsilyl groups. 32,33…”
