A polymeric bis(di-p-anisylamino)fluorene hole-transport material for stable n-i-p perovskite solar cells. (15th February 2021) - Tremblay, Marie-Hélène
Abstract : Half-devices made with a norbornene homopolymer with hole-transporting 2, 7-bis(di- p -anisylamino)fluorene side chains exhibit improved light and heat stability in comparison to those incorporating spiro-OMeTAD. Abstract : A norbornene homopolymer with hole-transporting 2, 7-bis(di- p -anisylamino)fluorene side chains is compared to the widely used spiro-OMeTAD as a hole-transport material (HTM) in negative-intrinsic-positive (n-i-p) perovskite solar cells (PSCs). PSCs fabricated using p-doped homopolymer achieve a power conversion efficiency of 15.5%, comparable to that of cells incorporating p-doped spiro-OMeTAD as the HTM. However, half-devices made with the polymer exhibit improved light and heat stability in comparison to those incorporating spiro-OMeTAD.
