The adsorption of chloride ion on a Pt electrode depends on the ion concentration, Pt morphology, temperature, and electrode potential. The coverage of CP on Pt decreases when both temperature [147,148] and concentration [147] increase, and when electrode potential decreases [147,148]. At 20°C, the coverage of CP on polycrystalline Pt was found to be ca. 0.5 monolayers at 0.7 V and ca. 0.45 monolayers at 0.6 V, when CP concentration in the electrolyte was 10 M [147]. Stamenkovic et al. [149] found that Pt(lll) is more active than Pt(lOO) for both the ORR and the HOR when CP is present in the electrolyte. They attributed the differences in catalytic activities to a much stronger interaction of Cl j with the (100) sites than with the (111) sites, and they proposed that Cl d strongly adsorbed onto Pt(lOO) can simultaneously suppress both the adsorption of O2 and H2 molecules and the formation of pairs of Pt sites needed to break the 0-0 and H-H bonds. 

The relative importance of these mechanisms may vary depending on the conditions (discharge product morphology, temperature, current density, etc.). For example, some studies have speculated that charge transport in Li202 could be enhanced at extended defects, such as surfaces [57, 58, 82], grain boundaries [83], amorphous regions [32, 54], or interfaces [81, 84]. 

The properties of eharge carriers in semiconductors depend on material morphology, temperature and material properties such as the crystal structure, band gap, dieleetrie funetion and carrier-lattice interaction. Much progress has been made in the past two decades in understanding the physics of elementary eleetronie excitations and carrier dynamics in the THz frequency range. A description of this work is outside the scope of the present chapter so we refer the reader to several reviews published on this topic. In this section, we will only introduce different theoretical models which are suited to describing the THz response of charge carriers in semiconductor systems commonly employed in solar cell architectures. 

The nucleation, growth, and morphology of crystals are influenced by both temperature and stress. 

Sodium Poly(4-styrene sulfonate). The sol—gel processing of TMOS in the presence of sodium poly-4-styrene sulfonate (NaPSS) has been used to synthesize inorganic—organic amorphous complexes (61). These sodium siUcate materials were then isotherm ally crystallized. The processing pH, with respect to the isoelectric point of amorphous siUca, was shown to influence the morphology of the initial gel stmctures. Using x-ray diffraction, the crystallization temperatures were monitored and were found to depend on these initial microstmctures. This was explained in terms of the electrostatic interaction between the evolving siUcate stmctures and the NaPSS prior to heat treatment at elevated temperatures.
