Interface Engineering of Perovskite Hybrid Solar Cells with Solution-Processed Perylene–Diimide Heterojunctions toward High Performance
Jie Min,Zhi-Guo Zhang,Yi Hou,Cesar Omar Ramirez Quiroz,Thomas Przybilla,Carina Bronnbauer,Fei Guo,Karen Forberich,Hamed Azimi,Tayebeh Ameri,Erdmann Spiecker,Yongfang Li,Christoph J. Brabec +12 more
TL;DR: In this paper, a solution-processed perylene-diimide (PDINO) was used as cathode interface layer between the [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) layer and the top Ag electrode.
Journal ArticleDOI
Overcoming the Interface Losses in Planar Heterojunction Perovskite-Based Solar Cells.
Yi Hou,Wei Chen,Derya Baran,Tobias Stubhan,Norman A. Luechinger,Benjamin Hartmeier,Moses Richter,Jie Min,Shi Chen,Cesar Omar Ramirez Quiroz,Ning Li,Hong Zhang,Thomas Heumueller,Gebhard J. Matt,Andres Osvet,Karen Forberich,Zhi-Guo Zhang,Yongfang Li,Benjamin Winter,Peter Schweizer,Erdmann Spiecker,Christoph J. Brabec +21 more
TL;DR: A scalable, hysteresis-free and planar architecture perovskite solar cell is presented, employing a flame spray synthesized low-temperature processed NiO (LT-NiO) as hole-transporting layer yielding efficiencies close to 18%.
Journal ArticleDOI

Journal ArticleDOI
Coloring Semitransparent Perovskite Solar Cells via Dielectric Mirrors
Cesar Omar Ramirez Quiroz,Carina Bronnbauer,Ievgen Levchuk,Yi Hou,Christoph J. Brabec,Karen Forberich +5 more
TL;DR: The design rules that consider the color efficiency/transparency interplay for real applications are established, enabling one to tailor the device appearance to almost any desired color and simultaneously offers additional light harvesting for the solar cell.
Journal ArticleDOI
Pushing efficiency limits for semitransparent perovskite solar cells
