Developing next generation quantum dot solids for photovoltaics


Quantum dot photovoltaics have the potential to exceed theoretical efficiency limits of other photovoltaic devices and represent a potentially disruptive next-generation technology. In this thesis I present my efforts to develop and characterize novel quantum dot materials that have superior multi-exitonic, optical, and electronic properties. Several methods for the synthesis of inverse type-II core shell quantum dots are explored and their associated challenges are presented. A variety of materials characterization techniques are implemented to investigate these materials. Lastly, a collaborative investigation of the electronic properties of high performance lead sulfide quantum dots is presented.
