Finite-Difference Time-Domain Simulation Of Photovoltaic Structures Using A Graphical User Interface For Meep, Xin Tze Tee, Peter Bermel
Finite-Difference Time-Domain Simulation Of Photovoltaic Structures Using A Graphical User Interface For Meep, Xin Tze Tee, Peter Bermel
The Summer Undergraduate Research Fellowship (SURF) Symposium
There is a large and growing need for accurate full-wave optical simulations of complex systems such as photovoltaic (PV) cells, particularly at the nanoscale. A finite-difference time-domain tool known as MEEP offers this capability in principle, through C++ libraries and the Scheme programming language. For expert users, this approach has been quite successful, but there is also great interest from new and less frequent users in starting to use MEEP. In order to facilitate this process, we have developed a graphical user interface (GUI) for MEEP, geared toward simulation of 2D and 3D PV cell geometries, freely available through a …

The Summer Undergraduate Research Fellowship (SURF) Symposium
The Stanford Stratified Structure Solver (S4) developed in 2012 allows for fast, accurate prediction of optical propagation through complex 3D structures. However, there have been two key challenges preventing wider use to date: the use of a specialized control language, and the difficulty of incorporating realistic materials parameters. In this project, both concerns have been addressed. We have constructed a graphical user interface as an alternative, using the open-source Rappture platform on nanoHUB. This has been combined with a comprehensive materials database known as PhotonicsDB, which incorporates materials optical data drawn from carefully vetted sources. An Octave script file was …
