Additionally, the charge carrier
concentration of the PEDOT: PSS film in this study is higher than the one previously reported for PEDOT:PSS films .
It leads to competition of tunneling through a potential barrier with charge carriers
activated at the percolation level [34, 35].

mobility in organic semiconductors," Journal of Polymer Science Part B: Polymer Physics, vol.
These include Poisson's equation, which relates the position-dependent electrostatic potential to charge carrier
densities that are also function of position within the solar cell device [17, 116].
The interpretation of this fact is that the polymeric chains of silver nanoparticles act as traps for the electronic charge carriers
which transited by hopping process [7, 8].
It can be seen that the ionic conductivity increases with the addition of AA which can be attributed to the increase in the number of mobile charge carriers
(ii) The result [D.sub.eff] = [D.sup.[section]] + [D.sup.*], actually inferred in : the interaction of the charge carrier
with the stress field of one edge dislocation defines an effective diffusion coefficient [D.sup.eff] consisting of two terms, [D.sup.*] related to its interaction with the electric potential of the cell and [D.sup.[section]] related to its chemical gradient and interaction with the stress field of the dislocation.

recombination dynamics," Journal of Physical Chemistry, vol.
When the voltage bias is applied, a depletion region in the n-doped GaAs layer with lower charge carrier
density is formed.
As a result, holes become the majority charge carrier
; this is known as p-type doping.
The deposition of PEDOT : PSS polymeric films on the free surface of CISCuT layers results in a small decrease in the height of the potential energetic barrier (the corresponding shift in the range of the space charge in the polymer layer) and an increase in the efficiency of charge carrier
transport through the CISCuT/polymer interface.
It is thought that the conductivity sensitively affects the humidity sensor property, especially under the high RH condition (over 75% RH), because the charge carriers
were able to move continuously on a well-formed water layer , However, it is still not obvious below 67% RH for the samples of 1 and 2% LiCl, owing to the intrinsic high resistance of the polymer.
