Solcore

- Solve a bug in the way front surface reflexion was calculated in the PDD model: it was using just the real part of the refractive index and not complex refractive index.
- Added the possibility of calculating the optical properties of a solar cell in the PDD model using the TMM formalism or providing an external generation profile as input for the solver under illumination. Note: It only works properly when using very dense, non-dynamic meshes.
- A structure for the PDD solver now can include layers defined as "optics" and "metal" that can be used to calculate the opticla properties but will be ignored y the electrical solver.
- Added the description of most functions of the PDD solver.
- Created new version of the MJ current voltage calculator, as the previous one didn't work in the dark.
- Added tests for the new MJ current voltage calculator
- Added test for the TMM optics calculator of the PDD solver
- Included an option in the TMM calculator (no_back_reflexion) to prevent reflexion from the back surface.
- Added a filter option for the PDD.Illumination object that accept an arbitrary function as filter.

- Removed all mention to the Mod CPPB calculator (test, examples, module and data in “absorption_calculator”)
- Moved all material information to the “materials_data” folder.
- SOPRA database moved to the “materials_data” folder. Module modified accordingly. Test added.
- Added the ellipsometry fitting routine to the "data_analysis_tools" package.
- Added Science_Tracker for the reference_spectra. Reference_spectra changed to function.
- Added documentation concerning the SOPRA database and the transfer matrix calculator

- Added new dielectric models to the absorption_calculator package
- Minor bug fixing

- Added the Modified_CPPB module to the absorption_calculator package.
- Two example files added to AC_examples.
- test_Modified_CPPB added to tests folder.

- Added Custom_Colours module to graphing package for adding a splash of colour to individual and multiple plots.
- Added a Custom_Colours example file to the examples folder.

- Added SOPRA database of optical constant data to the absorption calculator package. Package now contains a folder
of SOPRA raw data and documentation and a module file containing the sopra_database.
