ABSTRACT

 

        EngDSSC project fully addresses the main objective - Secure, Clean and Efficient Energy of ENERGY Theme in Horizon 2020. In this multidisciplinary, joint project, related to the very hot topic of solar energy conversion, two partners will work on dye-sensitized solar cell (DSSC) technology, the leading photovoltaic technology among the 3rd solar cells generation. The aim of this project is to obtain a competitive DSSC prototype by molecular engineering of new sensitizers. To this goal, the DSSC configuration will be engineered using our strong know-how in chemistry and physics. To achieve a high efficiency DSSC, new molecularly engineered dyes, cell design and technological approaches will be developed. The overall work plan comprises activities ranging from the material design (TRL2) to the DSSCs prototype validation (TRL4). The specific targets are the optimization of the push-pull dyes by our synthetic methods, their structural, photo-optical and electrochemical characterization, HOMO/LUMO levels and energy bandgap evaluation, so as to get the best sensitizers for DSSC manufacturing. Validation of the energetic compatibility between the cell’s elements, proof of the charge transfer, finding the best solution for TiO2 functionalization are the key activities whereupon the technology for DSSCs prototype fabrication will be developed. The recombination mechanisms, quantum efficiency and cell efficiency will be evaluated. As last activity, cell optimization will be performed by hole transport modulation and tuning of both the functionalization solution and electrolyte composition. The goal is to go beyond 5% efficiency, a key objective of the project.
