The people behind Quokka3.
Quokka3 is a commercial-quality rebuild and enhancement of the popular free solar-cell simulation tool Quokka. It is developed and maintained by AF Simulations GmbH.
From Quokka to Quokka3
The original Quokka was created at the Australian National University and, after its free release in 2013, became a widely used tool for multidimensional silicon solar cell simulation. That free version remains available today, hosted on PV Lighthouse.
Quokka3 is its commercial successor: a from-scratch rebuild aimed at commercial-quality robustness, broader physics, and full 3D device simulation. Its core development was carried out under a Marie-Skłodowska-Curie fellowship within the European Union's Horizon 2020 programme, and it is developed and maintained by AF Simulations GmbH.
Quokka's models are documented in a series of peer-reviewed papers, and the simulator underpins a broad body of solar-cell research. See Publications for the methodology references and a selection of the work that uses Quokka3.
Team
Andreas Fell
Andreas founded Quokka3 and is the author of the Quokka simulators. He completed his PhD at Fraunhofer ISE on laser processes for silicon solar cells, then worked at the Australian National University from 2011 to 2015, where he created the original Quokka. He held a Marie-Curie fellowship dedicated to Quokka3, and today leads AF Simulations GmbH while keeping a part-time senior-scientist role at Fraunhofer ISE, focused on silicon and silicon-based tandem cells.
His work on solar-cell modelling spans more than 150 peer-reviewed publications, and over the past decade Quokka has become a standard simulation tool across much of the silicon PV industry and research community. It is this hands-on, application-driven modelling expertise that licensed users draw on when they need support with their specific cells.
