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

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...
