Formate as Anti-Oxidation Additives for Pb-Free FASnI(3) Perovskite Solar Cells

Jinhyun Kim, Jaeki Jeong, Jiyoun Seo, Jiwon Kim

Pb-free Sn-based perovskite solar cells (PSCs) have significant potential for application in photovoltaic devices because oftheir suitable bandgap, low exciton binding energy, high carrier mobility, and long diffusion length. However, their performance is ...

Boosting the performance of Cu2O photocathodes for unassisted solar water splitting devices

Jinhyun Kim, Ulf Anders Hagfeldt, Jingshan Luo, Matthew Thomas Mayer, Amita Ummadisingu, Linfeng Pan, Minkyu Son

Although large research efforts have been devoted to photoelectrochemical (PEC) water splitting in the past several decades, the lack of efficient, stable and Earth-abundant photoelectrodes remains a bottleneck for practical application. Here, we report a ...

Long-Range π-Conjugation in Phenothiazine-containing Donor-Acceptor Dyes for Application in Dye-Sensitized Solar Cells

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Carole Graetzel, Jinhyun Kim, Thomas Moehl, Mateusz Barnaba Wielopolski, Yuxiang Yu

Four organic donor–π-bridge–acceptor dyes containing phenothiazine as a spacer and cyanoacrylic acid as an acceptor were synthesized and tested as sensitizers in dye-sensitized solar cells (DSCs). The influence of iodide- and cobalt-based redox electrolyte ...

Position-Dependent Extension of π-Conjugation in D-π-A Dye Sensitizers and the Impact on the Charge-Transfer Properties

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Jinhyun Kim, Thomas Wesley Holcombe, Mateusz Barnaba Wielopolski, Yuxiang Yu

A series of five organic donor-π-bridge-acceptor (D-π-A) sensitizers is investigated within the context of their photoinduced charge-transfer properties. Thereby, the focus is set on the impact of structural modifications of the molecular architecture on t ...

A feeder-free, defined three-dimensional polyethylene glycol-based extracellular matrix niche for culture of human embryonic stem cells

Jinhyun Kim, Jeffrey Alan Hubbell, Seung Tae Lee

We report optimization of a serum- and feeder-free, three-dimensional (3D) niche created with a synthetic polyethylene glycol (PEG)-based extracellular matrix for self-renewal of human embryonic stem cells (hESCs). Three hESC lines (H9, H1 and Novo) were c ...
