Dr Lethy Krishnan Jagadamma, Leader of the Energy Harvesting Research Group, University of St Andrews, UK
“In our Energy Harvesting Research Group, we have started using both PAIOS and SETFOS for the characterization of perovskite solar cells very recently. We find both tools very helpful in understanding the device physics of perovskite solar cells and different kinds of charge carrier losses through recombination. The multitude of characterization facilities such as light intensity-dependent J-V, Capacitance-Voltage measurement, transient photovoltaic and transient photocurrent, impedance measurement and charge transport characterization such as SCLC and CELIV all integrated into one set-up is so versatile to give an overview of different loss mechanisms and strength of one device structure over the other. Our research is particularly focussing on indoor photovoltaic development where the carrier management is stringent due to the low intensity and low carrier concentration. We have found PAIOS an excellent supportive tool to enhance our research.”

Dr. Ding, OLED simulation team, Ningbo Research Institute, China
“Our team purchased the optical and electrical modules of Setfos. The operation interface of the software is intuitive, friendly, and easy to operate. The software itself contains rich information within a large material database. In the OLED device simulation process, we can simulate the emission spectrum of OLED, and simultaneously the recombination zone of charge transfer and drift spread. It can also help us to modify the design of device structure and can effectively analyze and improve the OLED device efficiency. The results calculated by Setfos could be served as a good reference point for our scientific research. We would highly recommend you consider Setfos as the option. “

“Paios and Setfos have been an asset to our research capability in CSIRO Energy and a key tool in our research and assessment of next generation thin-film photovoltaics, in particular, organic and perovskite solar cells. One of the key points of differentiation – and a clear attraction – has been the flexibility of the system and the ease in which user-defined experiments can be created. Our Team has appreciated the interaction with Fluxim and realised this has been much more than a transactional experience – we’ve formed a real partnership between developers and researchers.”
-
Dr. Jan Blochwitz-Nimoth CTO Novaled AG, Dresden, Germany
“The setfos software is a fundamental optical simulation tool for the development of highly efficient OLED structures. New features of this software like including several different emission zones are of major importance for developing efficient white light OLED structures containing more than one emitting material. The flexibility, speed, and reliability of this software combined with its huge variety of simulation tools concerning various physical key quantities like angular dependence, color coordinates, or reflection spectra allow further improvement and basic insight of OLEDs.”

Dr. Markus Regnat, ZHAW School of Engineering, Switzerland
“As an OLED researcher, I am very thankful for the Fluxim tools we have in our Group at ZHAW. Thanks to Paios and Phelos I can characterize my OLEDs in various regimes, such as transient, frequency, or steady-state and angle-dependent, and this all by just a few clicks. Thanks to the simulation software Setfos I can set up an electro-optical device model to reproduce the experimental data, which helps me to understand better the physics inside the OLED. Knowing the emission zone or the charge carrier distribution of an OLED can give you hints on efficiency or lifetime improvements.”

I'm using Setfos from more than 8 years now. It's really an essential tool we're using each days. We are using it to :
- design OLED stacks, taking into account emitter intrinsic spectra, n&k transport and blocking layers
- each time we need to adjust OLED optical cavity
The software is really user friendly. We are not using the electrical addon but maybe it could be interesting too.
