Dopant-free polymeric hole transport materials for highly efficient and stable perovskite solar cells

Autor: Jinseck Kim, Gang-Young Lee, Limok Pyeon, Jae-Chol Lee, Guan-Woo Kim, Gyeongho Kang, Taiho Park, Hong Il Kim

Publikováno v: Energy & Environmental Science. 9:2326-2333

We report a dopant-free polymeric hole transport material (HTM) that is based on benzo[1,2-b:4,5:b′]dithiophene and 2,1,3-benzothiadiazole, which results in highly efficient and stable perovskite solar cells (∼17.3% for over 1400 h at 75% humidit

Parameters influencing the molecular weight of 3,6-carbazole-based D-π-A-type copolymers

Autor: Sang-Jin Moon, Taiho Park, Jinseck Kim, Ayyanar Siva, Yuanhe Fu, Won Suk Shin

Publikováno v: Journal of Polymer Science Part A: Polymer Chemistry. 49:4368-4378

Condensation copolymerization reactions of carbazole 3,6-diboronate with 4,7-bis(5-bromo-2-thienyl)-2,1,3-benzothiadiazole (DTBT) only produce low-molecular-weight donor (D)-π-acceptor (A) copolymers. High-molecular-weight copolymers for use in opto
