Single Molecule Studies of Initial Steps in Dye Sensitized Solar Cells and of Quantum Dots – Examples of Electron Transfers and Relation to Ensemble Studies

by Rudolph Marcus
Single Molecule Studies of Initial Steps in Dye Sensitized Solar Cells and of Quantum Dots – Examples of Electron Transfers and Relation to Ensemble Studies
for 18-22 and upwards,
Lectures | 18-22 and upwards | 9 years ago | 1607 views
Rating:

We consider two fields of single molecule studies of intermittently fluorescing systems.  In both fields the intermittency is assumed to involve diffusion controlled electron transfer.  One of these studies involves the initial steps in dye-sensiti....
