Abstract
In here we report on using flash photolysis, time-resolved microwave conductivity (fp-TRMC) as a tool for detecting the fate of mobile charge carriers. This spectroscopy does not require electrodes and can therefore focus attention on the active components of the donor- acceptor system and provide insight into the heart of OPV device functionality.
