Morphologically controlled ZnO nanostructures as electron transport materials in polymer-based organic solar cells

Autor: Yangdo Kim, Dong Chan Lim, Kyu-Chae Choi, Yong-Cheol Kang, Youn-Kyoung Baek, Youngkuk Kim, Eun Jin Lee, Ki-Hyun Kim, Kim Jaepil

Publikováno v: Electrochimica Acta. 180:435-441

The morphology of ZnO electron transport layers based on ZnO nanoparticles were modified with incorporation of ZnO nanorods via their co-deposition from mixed colloidal solution of nanoparticles and nanorods. In particular, the short circuit current

Enhanced luminescence stability of quantum dot-based inorganic nanocomposite particles for white-light-emitting diodes

Autor: Youngkuk Kim, Youn-Kyung Baek, Pyung-Woo Shin, Kyu-Chae Choi

Publikováno v: Materials Letters. 124:129-132

We have synthesized quantum dot (QD)-embedded inorganic nanocomposites by effective combination of spray pyrolysis and subsequent sol–gel processing. The rapid depression of emission intensity of QDs just after addition of ammonia for sol–gel pro

Modifying hydrogen bonding interaction in solvent and dispersion of ZnO nanoparticles: impact on the photovoltaic performance of inverted organic solar cells

Autor: Yangdo Kim, Youngkuk Kim, Min-Ji Kim, Kyu-Chae Choi, Yeon-Kyung Baek, Eun Jin Lee, Pyung-Woo Shin

Publikováno v: RSC Advances. 4:7160

We demonstrate that the morphology of ZnO buffer layers for the inverted organic solar cells (IOSC) was improved by controlling the molecular interaction in solvents to disperse ZnO nanoparticles (NPs). Dispersion of ZnO NPs in non-polar solvent usua
