Lecture

Solid State Chemistry

• Crystal structures, symmetry, and diffraction basics (XRD as a structural tool)

• Bonding in solids and crystal chemistry (ionic/covalent/metallic; lattice energy concepts)

• Defects & non-stoichiometry (point defects, Kröger–Vink notation, defect equilibria)

• Phase diagrams and thermodynamics of solids

• Transport phenomena in solids (diffusion, ionic/electronic conduction)

• Structure–property relationships in functional solids (ceramics, batteries, catalysts, semiconductors)

Photoelectrochemistry

• Semiconductor–electrolyte interface (band bending, Helmholtz layer, energetics)
  
  

• Light absorption and carrier generation (quasi-Fermi levels, recombination pathways)
  
  

• Charge separation/transport vs. interfacial charge transfer (kinetic vs transport limits)
  
  

• Photoelectrochemical cell operation (J–V under illumination, onset potential, efficiency metrics)
  
  

• Electrode stabilization strategies (protective layers, catalyst integration, passivation)
  
  

• Characterization toolbox (Mott–Schottky, IPCE/APCE, EIS, IMPS/IMVS, transient methods)
