Structural determination, solar materials surfaces

The cost-effective deployment of large areas of solar collectors will most probably be polycrystalline materials, with all index planes emerging at the surface. Therefore, it is not expected that the structural determination of solar materials surfaces will be applied except for a few special cases. However, determining S/S inter facial structures is important, as shown by Figs. 6-9 in Ref. 2. The challenge in solar interface research will be to understand the changes in surface activity of heterogeneous real surfaces and interfaces. Here, SEM and possibly STEM techniques should be used extensively. [Pg.333]

The deliberate modification of electrode surfaces by coating with one or more layers of electroactive material has been used for a variety of purposes. Solar energy conversion, electrochromism, corrosion protection, and electrocatalysis are but a few of the applications which are currently of interest. The use of in situ Raman spectroscopic studies can help to determine the structural characteristics of electrode coatings at the molecular level and can provide information on the mechanisms of electrochemical reactions occurring at modified electrode surfaces. [Pg.99]

LSPR frequency is dependent on the size, shape, material properties and the effect of the dielectric medium around the nanoparticles. They determine the position and width of the plasmon resonance. Due to the confinement of the SP to the metal nanoparticle, excitation of surface plasmons can result in selective photon absorption, scattering and a large enhancement of the local electric field in the close vicinity of the metal nanoparticles. Hence, varying these parameters offers the tunable resonance position to engineer plasmonic structures to target weakly absorbing regimes of various types of solar cells [5]. [Pg.120]
