Products of Organic Electronics and Photovoltaics are successfully penetrating consumer electronics and renewable energy markets. Commercialization is accelerating continuously and everyone can enjoy amazing new products to buy, for instance stunning OLED displays for mobile devices and TVs as well as flexible organic solar cells. With the commercial success of OLED display products and the rise of perovskite solar cells one may be tempted to disregard the many research challenges that we are still facing in this field and which prevent an even wider exploitation of these technologies.

The challenges are manifold. So are the synthetic materials these technologies are based on. Physical models and simulation algorithms are very useful in this context. They enable scientists to explore the behavior of a material or device on a computer. On the one hand, the numerical models help to understand and interpret measurement data and to further develop refined and reliable physical models. On the other hand, the models allow one to optimize materials and devices. Progress in this field relies on an interdisciplinary approach that combines experimental, physical, chemical and numerical expertise.

The motivation of this unique conference is to bring together these experts and enjoy a fruitful scientific exchange among them that will focus on a comprehensive range of topics. This will eventually lead to ever more reliable, validated physical models which accelerate our research efforts. We are pleased to chair this conference that continues a series of successful international simulation workshops on this topic previously held in Switzerland (2010, 2011, 2016, 2018, 2020) and Spain (2012, 2014).

This year, the event will again be held physically in Winterthur after the online edition of SimOEP’20. Fluxim’s R&D tools will be exhibited and demonstrated during the event.

Mixed Ionic-Electronic Conductivity in Perovskites Workshop

On the first two days of the conference, the Mixed Ionic-Electronic Conductivity in Perovskites Workshop will be held after the SimOEP program. This workshop is organized by Dr. Wolfgang Tress and covers various topics related to perovskites.

The participation in this workshop is included in the access to the SimOEP' 22 conference and is based on the ERC-project OptElon (Defect Engineering, Advanced Modelling and Characterization for Next Generation Opto-Electronic-Ionic Devices).
