# This program calculates the field profile, exciton generation profile
# and generated current from the wavelength dependent complex indicies of
# refraction in devices using the transfer matrix method. It assumes the light source
# light source is in an n=1 environment (air) and that the first layer is
# a thick superstrate, so that incoherent reflection from the air/1st layer
# interface is taken into account before the coherent interference is
# calculated in the remaining layers. If there is no thick superstrate,
# input 'Air' as the first layer so that the incoherent reflection calculates
# to 0.
# The program
# also returns the calculated short circuit current for the device in
# mA/cm^2 if the device had an IQE of 100%.
# The procedure was adapted from J. Appl. Phys Vol 86, No. 1 (1999) p.487
# and JAP 93 No. 7 p. 3693.

# Thin Solar Cells
# Modifications:
# 3/3/11 Parastic absorption (parasitic_abs) is calculated and made
# accessable outside of script.
## USER CONFIGURATION
# Build up the device, light enters from left to right, the layer names
# correspond to the csv filenames in the 'matDir' ignoring the material prefix.
# example : you have a material file named 'nk_P3HT.csv' the layer name would be 'P3HT'
# Layer thicknesses are in nm.
layers    = ['SiO2' , 'ITO' , 'PEDOT' , 'P3HTPCBM_BHJ' , 'Ca' , 'Al']
thicknesses  = [0 , 110 , 35  , 220 , 7 , 200]
plotGeneration = True  # Make generation plot , True/False
activeLayer  = 3   # indexing starts from 0
lambda_start = 350 # build a wavelength range to calculate over, starting wavelength (nm)
lambda_stop  = 800 # final wavelength (nm)
lambda_step  = 5  # wavelength step size
plotWavelengths = [400 , 500 , 600]  # Wavelengths to plot |E|^2 for, in nm.
# this is where the n/k optical constants for each material are stored.
# file format is : CSV (comma separated values)
# each materials file is prefixed with 'nk_' and the first 'matHeader' number of lines are skipped.
matDir   = 'matdata' # materials data
matPrefix  = 'nk_'  # materials data prefix
