Sub-10-fs observation of bound exciton formation in organic optoelectronic devices

Autor: Marios Maimaris, Allan J. Pettipher, Mohammed Azzouzi, Daniel J. Walke, Xijia Zheng, Andrei Gorodetsky, Yifan Dong, Pabitra Shakya Tuladhar, Helder Crespo, Jenny Nelson, John W. G. Tisch, Artem A. Bakulin

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-10 (2022)

Ultrafast action spectroscopies of organic optoelectronic devices reveal that the formation of bound exciton state occurs as fast as 10 fs. Excitons having excess energy can dissociate spontaneously within 50-fs before acquiring bound character.

Influence of static disorder of charge transfer state on voltage loss in organic photovoltaics

Autor: Jun Yan, Elham Rezasoltani, Mohammed Azzouzi, Flurin Eisner, Jenny Nelson

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-12 (2021)

Charge transfer state provides insight into energy loss in organic photovoltaics, which is dictated by molecular vibrations and static disorder. Here, the authors propose a method for exploring the effect of donor/acceptor interface microstructure on

Color-tunable hybrid heterojunctions as semi-transparent photovoltaic windows for photoelectrochemical water splitting

Autor: Flurin Eisner, Brian Tam, Valentina Belova, Wesley Ow, Jun Yan, Mohammed Azzouzi, Andreas Kafizas, Mariano Campoy-Quiles, Anna Hankin, Jenny Nelson

Publikováno v: Cell Reports Physical Science, Vol 2, Iss 12, Pp 100676- (2021)

Summary: The strong but narrow-bandwidth absorption spectra of organic semiconductors make them excellent candidates for semi-transparent solar cell applications in which color specificity is important. In this study, using a hybrid heterojunction co

Driftfusion: an open source code for simulating ordered semiconductor devices with mixed ionic-electronic conducting materials in one dimension

Autor: Philip Calado, Ilario Gelmetti, Benjamin Hilton, Mohammed Azzouzi, Jenny Nelson, Piers R. F. Barnes

Publikováno v: Journal of Computational Electronics. 21:960-991

The recent emergence of lead-halide perovskites as active layer materials for thin film semiconductor devices including solar cells, light emitting diodes, and memristors has motivated the development of several new drift-diffusion models that includ

Relationship between molecular properties and degradation mechanisms of organic solar cells based on bis-adducts of phenyl-C61 butyric acid methyl ester

Autor: Xueyan Hou, Andrew J. Clarke, Mohammed Azzouzi, Jun Yan, Flurin Eisner, Xingyuan Shi, Mark F. Wyatt, T. John S. Dennis, Zhe Li, Jenny Nelson

Publikováno v: Journal of Materials Chemistry C. 10:7875-7885

Environmental stability remains a major challenge for the commercialisation of organic solar cells and degradation pathways remain poorly understood. Designing materials for improved device stability requires an understanding of the relationship betw

Non-fullerene acceptors (NFAs) are excellent light harvesters, yet the origin of their high optical extinction is not well understood. In this work, we investigate the absorption strength of NFAs by building a database of time-dependent density funct
