Paper on Non-Equilibrium Voc Finally Published

Great news! After several rounds of review, which included a change of the title, our study on the effect of slow carrier relaxation on the open-circuit voltage of organic solar cells (see previous entry) has now finally been published in the Journal of Physical Chemistry Letters. In the article we argue that the open-circuit voltage […]

Presentation at Uppsala University

Last week Sebastian gave an invited talk in the Solar Cell Technology Group at Uppsala University in Sweden. Due to the current restrictions caused by the COVID-19 pandemic, the event took place virtually. The topic of the talk was recombination in organic solar cells and many results from ReMorphOPV were included in the presentation. The […]

Kinetic Monte Carlo Model Describes Organic Solar Cell Current–Voltage Curve

Kinetic Monte Carlo (KMC) simulations are a powerful tool to describe microscopic processes in disordered materials such as charge carrier transport and recombination. However, describing the macroscopic performance of complete devices such as organic solar cells has proven exteremely challenging. In our latest paper published in Solar RRL, we introduce a KMC model that is […]

ReMorphOPV moved to Åbo Akademi University

As of today, the ReMorphOPV project is at home at Åbo Akademi University in Turku, Finland. The research is carried out in Prof. Ronald Österbacka’s group at the Faculty of Science and Engineering. The change of the hosting organisation was necessary because the previous host research group at Linköping University was discontinued. The goals and […]

Watching Space Charge Build Up in an Organic Solar Cell

Space charge effects in the active layer usually lead to a degraded device performance of organic solar cells. In principle, there are two possible reasons for the build-up of space charge: unintentional doping and imbalanced charge transport. Although these are fundamentally different phenomena, they lead to the very same degradation of the device current-voltage curve, […]

nanoGe Fall Meeting in Berlin

Sebastian presented our latest results on kinetic Monte Carlo simulations of organic solar cells at the 2019 nanoGe Fall Meeting held from 4 to 8 November in Berlin. The nanoGe Fall Meeting is a unique series of focused symposia on fundamental properties and preparation of advanced materials and their applications in fields such as photovoltaics […]
