TopicSinglet fission in organic semiconductors for solar cells.
AnnotationSinglet fission (SF) is the process in which a photoexcited molecule in an organic solid shares its energy with a neighboring unexcited molecule to produce a correlated pair of excited molecules. Recently, the SF was identified as a promising way of increasing the theoretical limit of power conversion efficiency in solar cells. The work will be focused on the experinmental study of the process of singlet exciton fission in acene and perylenediimide derivatives In this research we want to exploit the rich supramolecular structure variability of these materials in solid phase to manipulate the kinetics of the SF. An ultrafast transient absorption laser spectroscopy will be used as a main tool for this study. The work will be aimed to increase the power conversion efficiency of organic solar cells but also to contribute to the knowledge of the excited state dynamics in this type of organic compounds. The topic is suitable for students with completed master studies in physical chemistry, polymer and chemical physics, or biophysics.
