All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

v1.2.6

Changed

removed manual time stepping in all perovskite solar cell examples

Fixed

displacement current was missing in current calculation

v1.2.5

Changed

removed pause call in plot_IV

v1.2.4

Changed

Cleanup of return values of plotting functions, all return nothing now.
no implicit show call in potting functions; do this explicitly if needed

v1.2.3

Changed

Density of states and mobilities are by default now set one, while band edge energies are set to zero.
If the user does not define data.bulkRecombination, by default recombination is set off. Caution: For semiconductor applications with electrons and holes, this method does method may still need to be initialized, e.g., when working with the Schottky barrier lowering boundary model.

v1.2.2

Added

In equilibrium_solve!(), we have now two additional inputs: verbose and yabstol to control the secant method for finding vacancy energy levels

v1.2.1

Fixed

Fixed broken math mode in docs
fixed some plotting, by properly including parameters
fixed unnecessary photogeneration loop in notebook

v1.2.0

Added

Modified equilibrium_solve!(). Directly computes now the correct energy level such that the average vacancy density matches the user-defined target, if the argument is vacancyEnergyCalculation = true. Check the package documentation for more information
Added method integrated_density, which computes the integrated carrier density for a given species icc and region ireg
Extended Data structure with data.regionVolumes, which stores the volume (measure) of each subregion

Changed

loop for increasing photogeneration rate is now also included internally, see Ex103. There is now no need to do this by the user.

v1.1.0

Fixed

fixed broken v1.0.0 release

v1.0.0

Added

Params can be constructed with numberOfRegions, numberOfBoundaryRegions and numberOfCarriers
Params can be constructed directly from problem specific parameter structs

Changed

parameter files are replaced by parameter structs with explicit parameter access: p = parameter_set(); p.foo to access parameter foo; you can specify in the examples which parameter_set is used.
all examples scripts are overhauled with the new parameter set usage
global unit factors are removed: we rely on local unit factors from LessUnitFul.jl, provided by @local_unitfactors and ufac""
new globally available dimensionless constants object, containing the default physical constants
new application specific teSCA_constants, pdelib_constants, unit_constants are also available
Data needs a constants object as a key word argument, defaults to standard constants
notebook folder name from pluto-examples to notebooks

Removed

Thermal voltage UT is no longer part of the Params, since this value may depend on different definitions of the elementary charge q
methods taking UT as an argument take the temperature now instead
exported global physical constants
enable_trap_carrier!() method as the underlying model and discretization were not correctly set up

v0.6.0 July 23, 2025

Fixed

documentation via Documenter.jl

v0.5.0 July 17, 2025

Added

functions for internal data handling: datadir, examplesdir, parametersdir
possibility to add a stimulated recombination term for laser applications
struct ParamsOptical to hold fields for laser applications

Fixed

correct inclusion of parameter files independent of folder, from which they are started
corrected definition of numberOfNodes in function ParamsNodal

Changed

adjusted argument inival for function equilibrium_solve! to be inserted if desired

v0.4.0 May 26, 2025

Changed

adjusted global (constants and units) are mutable globals now for compatibility with julia 1.2 (will change with a proper export in upcoming 1.0 release)

v0.3.0 April 29, 2025

Added

code quality checks
Runic code formatting
post-process methods
