On this page we offer you software developed at ISFH for download.
DHGpy (free of charge according to license agreement)

DHGpy is a tool based on Pandapipes, which allows for designing and thermohydraulic simulations of district heating grids with a current focus on “Kalte Nahwärme” (5th generation district heating).

This is currently only the first running version with a workflow with csv-files and QGIS.

ISFH components for thermal system simulation with TRNSYS

ISFH has developed a series of components for the representation of thermal and electrical system technology for the simulation environment TRNSYS. We provide a selection of the generated types free of charge.

How do I get such a type? Please download the respective license agreement and fax it filled out with your e-mail address to 05151-999-500 or send it to s.schiewe@isfh.de. We will then email you the type.

SEGA GUI (free of charge according to license agreement)

In the research of industrial silicon solar cells the gap to the theoretical efficiency limit of about 29% closes gradually. State-of-the-art industrial PERC cells achieve efficiencies around 22% leaving only 7% efficiency improvement potential.

Closing this gap further is a challenging task for cell developers. The identification of the most promising cell properties for the further research is an important aspect of the development process. The SEGA-GUI, which can be downloaded below, addresses this task by enabling researchers to perform synergistic efficiency gain analyses (SEGA) without any programming knowledge and on short timescales. Here the solar cell is simulated one time with the parameter as in a reference simulation and one time with the parameter idealized.

The difference of the energy conversion efficiencies is the improvement potential due to this parameter. This approach also enables the analysis of synergistic effects between different loss channels. Also partly deactivated loss channels can be analyzed. The input required for performing a SEGA is a set of easily measurable cell properties including resistances and recombination currents. The optical properties of the cell can be determined from a measured reflectance spectrum.
