Jung Kyu Kim, Dr. Insun Park, Wanjung Kim, Prof. Dong Hwan Wang, Dr. Dae-Geun Choi, Dr. Yeong Suk Choi and Prof. Jong Hyeok Park Enhanced Performance and Stability of Polymer BHJ Photovoltaic Devices from Dry Transfer of PEDOT:PSS ChemSusChem 7
Smoothing it over with a stamp: Bulk-heterojunction polymer solar cells with enhanced device performances and a long-term stability are fabricated using a simple dry transfer method. Due to the reverse poly(styrenesulfonate) (PSS)-enriched region in the transferred poly(3,4-ethylenedioxythiophene (PEDOT):PSS layer, its work function and morphology can be tuned. Furthermore, by avoiding direct contact between substrate and PEDOT:PSS solution, the stability is improved.
