  • Research Interests

My Ph. D. research has focusedon solutionprocessed organicsolarcellsfabricatedbynewly synthesized nanomaterialswithspecific opto-electronicproperties.Inparticular,my research workincludesthestudyofmorphology andinterfacialengineeringinorganic photovoltaics with different active layers. I have carried out research on various topics related to polymer/PCBM, small molecule/PCBM, polymer/polymer, small molecule/polymer active films and their molecular configuration of bulk heterojunctions or bilayer films, and the demonstration of charge carrier dynamics and kinetics in various active structures. Currently, I am especially interested in advanced research on eco-friendly organic solar cells.
