International Conference on Simulation of Organic Electronics and Photovoltaics, SimOEP 2018

The SimOEP conference brings together modeling experts and device physicists from industry and academia in the field of organic and perovskite solar cells as well as OLEDs. The addressed topics include charge and heat transport, exciton dynamics, light propagation and the simulation domain ranges from nanometer to centimeters.

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 the 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) and Spain (2012, 2014). This year, the event will again host hands-on training seminars with R&D tools from Fluxim AG.

How to get there

The conference will take place at the building TP at Technikumstrasse 9  in the heart of Winterthur. Situated 25 kilometers north-east of Zurich, Winterthur is Switzerland’s sixth largest city and offers a rich cultural life as well as excellent travel connections in all directions. It is located near Zurich’s international airport, which is only 20 minutes away by train or car.

We recommend travelling to the conference by public transport, since it can be easily reached by train or bus and we cannot offer any parking on campus. However, paid short- and long-term parking spots are available nearby. The main train station, which is served by numerous regional, national and international express trains, is only a short five-minute walk away.
