Autor: Soonil Hong, Hongkyu Kang, Geunjin Kim, Seongyu Lee, Seok Kim, Jong-Hoon Lee, Jinho Lee, Minjin Yi, Junghwan Kim, Hyungcheol Back, Jae-Ryoung Kim, Kwanghee Lee
Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-6 (2016)
The fabrication of organic photovoltaic modules usually relies on patterning techniques which limit their efficiencies. Here, the authors propose a module structure that avoids the patterning steps, and use doctor-blade printing and slot-die coating

Conjugated polyelectrolytes for stable perovskite solar cells based on methylammonium lead triiodide
Autor: Yong Ryun Kim, Juae Kim, Heejoo Kim, Hyungcheol Back, Geunjin Kim, Ayeong Gu, Chang-Yong Nam, Ju-Hyeon Kim, Hongsuk Suh, Kwanghee Lee
Publikováno v: Journal of Materials Chemistry A. 10:3321-3329
Despite the outstanding role of conjugated polyelectrolytes (CPEs) in organic solar cells, the use of CPEs in perovskite solar cells has rarely been reported due to instability issues of the material itself under operating conditions.

Long-Term Stable Recombination Layer for Tandem Polymer Solar Cells Using Self-Doped Conducting Polymers
Autor: Seyoung Kee, Hyungcheol Back, Soonil Hong, Hongkyu Kang, Song Yi Jeong, Geunjin Kim, Jinho Lee, Seoung Ho Lee, Junghwan Kim, Kwanghee Lee
Publikováno v: ACS Applied Materials & Interfaces. 8:6144-6151
Recently, the most efficient tandem polymer solar cells (PSCs) have used poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PSS) as a p-type component of recombination layer (RL). However, its undesirable acidic nature, originating from insulat
