Grapa

NOT RELEASED
- Read CSV export files of the SquidAdmiral system
- Implemented automatic processing of Jsc-Voc data. Careful, the fit limits may be quite off from reasonable values.
BUGS
- Modified the output of scriptJV so samples with name purely numerical correctly proceed through the script
- Solved a bug in script Cf that prevented the correct display of the map dC/dln(f) vs T vs frequency.
- Solved a bug in script CV that stopped the execution when for some reason, negative values of N_CV were computed.

Grapa is a python package providing a graphical interface and the underlying code dedicated to the visualization, analysis and presentation of scientific data, with a focus on photovoltaic research.

Additions
- New values possible for keyword "alter": 'y' and 'x', with combination ['y','x'] enabling graph transposition
- Curve Cf: the dataset can now be displayed as "Frequency [Hz] vs Apparent depth [nm]"
- Script Cf: the "Frequency [Hz] vs Apparent depth [nm]" is now automatically generated
- The "axhline" and "axvline" keywords can be used to specify the formatting, independently for different sets of lines. Examples are provided.

Bugs
- CurveJV: when creating a CurveJV object, an "area" parameter is set by default with value 1.
- Script process JV: a cause for exception and script failure was corrected, in case of missing data.
- Script process JV: script execution should be more robust with untypical data. Basic JV parameters should be extracted, and failures with JV fits should not affect script execution. Missing Rs, Jo and ideality values might result.
- Prevents the data editor to crash when first Curve contains too many data.

Additions
- A Nyquist plot is created when executing the script C-f.
- An image is created when executing the script C-f, showing the derivative as function of T and frequency.
- Shortcut were placed to tune the boxplot appearance: horizontal position, width of the boxes, presence of a notch, vertical or horizontal orientation.
- Keyboard shortcuts were added:
Ctrl+h: hide (or show) the active curve
Ctrl+Delete: delete the active curve
- References were added to the help function of CurveCf, papers from Walter, and Decock.

Modifications
- EQE ERE estimate now discplays the input Voc of the device as a double check
- In the script treating C-V data, the units of the apparent doping density are now properly displayed in [cm-3] units and not [m-3]
- An additional example is provided for the keyword colorbar
