Journal ArticleDOI
Toward Large Scale Roll‐to‐Roll Production of Fully Printed Perovskite Solar Cells
Kyeongil Hwang,Kyeongil Hwang,Yen-Sook Jung,Yen-Sook Jung,Youn-Jung Heo,Youn-Jung Heo,Fiona H. Scholes,Scott E. Watkins,Jegadesan Subbiah,David J. Jones,Dong-Yu Kim,Doojin Vak +11 more
TL;DR: A sequential slot-die coating process is developed to produce efficient perovskite solar cells and to be used in a large-scale roll-to-roll printing process, a scalable printing method.
Journal ArticleDOI
3D printer based slot-die coater as a lab-to-fab translation tool for solution-processed solar cells
Doojin Vak,Kyeongil Hwang,Kyeongil Hwang,Andrew Faulks,Yen-Sook Jung,Yen-Sook Jung,Noel Clark,Dong-Yu Kim,Gerard J. Wilson,Scott E. Watkins +9 more
TL;DR: In this paper, the authors used an industrial printer to produce BHJ solar cells and found that over 30 L of ink was required to start roll-to-roll production.
Journal ArticleDOI
Slot die coated planar perovskite solar cells via blowing and heating assisted one step deposition
Jueng Eun Kim,Jueng Eun Kim,Yen-Sook Jung,Yen-Sook Jung,Youn-Jung Heo,Youn-Jung Heo,Kyeongil Hwang,Kyeongil Hwang,Tianshi Qin,Dong-Yu Kim,Doojin Vak +10 more
TL;DR: In this paper, the authors introduced a blowing step in the slot-die coating method, which significantly improved the coverage of the prepared slots-die coated perovskite films and achieved a moderate power conversion efficiency (PCE) of 8.8%.
Journal ArticleDOI
Slot-Die Coated Perovskite Films Using Mixed Lead Precursors for Highly Reproducible and Large-Area Solar Cells.
Donmin Lee,Yen-Sook Jung,Youn-Jung Heo,Sehyun Lee,Kyeongil Hwang,Ye-Jin Jeon,Jueng Eun Kim,Jiyoon Park,Gun Young Jung,Dong-Yu Kim +9 more
TL;DR: It is observed that slot-die-coated perovskite films based on the mixed lead precursors exhibited well-grown and uniform morphology, which was hard to achieve by using only a single lead source.
Journal ArticleDOI
Printing-friendly sequential deposition via intra-additive approach for roll-to-roll process of perovskite solar cells
Youn-Jung Heo,Youn-Jung Heo,Jueng Eun Kim,Jueng Eun Kim,Hasitha Weerasinghe,Dechan Angmo,Tianshi Qin,Kallista Sears,Kyeongil Hwang,Kyeongil Hwang,Yen-Sook Jung,Yen-Sook Jung,Jegadesan Subbiah,David J. Jones,Mei Gao,Dong-Yu Kim,Doojin Vak +16 more
TL;DR: In this article, organic cation additives in lead iodide solutions are used for roll-to-roll production of perovskite solar cells, which is known to be more reliable than 1-step process.
