Photochemistry II: Photovoltaic Cells

This lecture covers the transition from dye-sensitized solar cells to double donor-acceptor heterojunction photovoltaic cells, exploring materials like N719, CH3NH3PbI3, and spiro-MeOTAD. It delves into the best research cell efficiencies, including thin-film technologies and emerging PV technologies. The lecture also discusses organic photovoltaics, conjugated polymer solar cells, and organic donor-acceptor bulk heterojunctions. Furthermore, it examines artificial photosynthesis strategies, molecular systems for solar energy conversion and storage, and photoredox water-splitting mechanisms. The lecture concludes with topics on molecular water photolysis for hydrogen production, charge recombination hampering, water-splitting using semiconductor photocatalysts, and photo-electrochemical hydrogen generation.
