Drift-diffusion simulations have proven very useful to understand the properties of novel devices such as perovskite solar cells. In order to make such simulations widely accessible and transparent, we have developed an open-software simulation suite called SIMsalabim.

SIMsalabim incorporates hysteresis, ions, and tracking of the open-circuit voltage, as well as the ability to include scripting for different measurement techniques such as CELIV, TPC, TPV, and impedance spectroscopy. This makes it possible to fit simulation results to experimental data, including global fits of multiple experiments. SIMsalabim is an open-source software, and its source code is accessible to all users. Moreover, to improve user experience and encourage its use by researchers in the field of photovoltaics, we have recently developed a web-version of SIMsalabim that runs in a web-browser [1]. Overall, this software is a powerful tool for researchers in the field of hybrid and organic photovoltaics to better understand the physical processes within their semiconductor devices.
