Lecture
This lecture covers the role of potential-controlling ions in determining the flatband potential at solid surfaces, as well as the mechanisms of light-induced charge separation at liquid and Schottky junctions. It also discusses the dye-sensitization of wide-bandgap semiconductors and the efficiency of charge separation processes. Furthermore, it explores the thermodynamic limitations of power conversion efficiency in solar energy conversion, emphasizing the impact of non-equilibrium conditions and entropy of light. The lecture concludes with insights into the quantum and bio-conversion of solar energy, highlighting the challenges and opportunities in renewable energy supply.
