Abstract

We synthesized thienyl-substituted carbazole-type self-assembled monolayers with different alkyl spacer lengths and evaluated their performance when used as hole transport layers in inverted perovskite solar cells. Among them, T-4PACz with butylene spacers showed the highest power conversion efficiency and thermal stability due to improved solubility and film formation.
