Development of innovative materials for high efficiency polymer solar cells

This PhD thesis was focused on the implementation of suitable strategies for the fabrication of polymer solar cells (PSCs) to improve the device performances. To this aim, several materials having specific chemical and physical properties were used, and new strategies for fabrication of solar cells were implemented using simple techniques of practical interest, in a view to develop feasible scale up processes. For each approach the efficiency limiting factors were identified, providing useful scientific basis for future investigations. Moreover, this work confirmed that the use of spontaneous block copolymers (BCPs) self-assembly is a potential strategy to create tailored organic nanostructures able to precisely incorporate inorganic semiconductor nanoparticles (NPs) into specific domains for the realization of active layers in the hybrid PSCs.
