Spiro-thiophene derivatives as hole-transport materials for perovskite solar cells

Abstract

This work reports a promising hole transporting material using a spiro-thiophene derivative with 4,4′-spirobi[cyclopenta[2,1-b;3,4-b′]dithiophene] as the spiro core for perovskite solar cells, exhibiting an overall power conversion efficiency of 10.4% with an open circuit voltage of 0.94 V, and a short circuit current density of 16.54 mA cm−2 under standard testing conditions.
