Project: Rational design of Self-Assembling networks for TRansparent electrode APplications

Acronym: SATRAP
Main Objective:
Quest for better and more affordable transparent electrode materials for next-generation opto-electronic devices is currently one of the most pursued goals in materials science. Carbon nanotubes has been long considered for this role, however current implementations, based on random films of nanotubes, lag behind more expensive alternatives in transparency and conductivity. The proposed work aims to exploit the recently discovered self-assembly of zinc-salphen compounds into neuron-like networks to align very small amounts of nanotubes thus creating films with improved characteristics. A multiscale computer study will be performed to fine tune the macroscale parameters of such networks' fabrication and their performance as transparent electrodes, supported by experimental validation using a state-of-art organic photovoltaic cell. This will allow production of advanced low-cost electrodes outperforming current alternatives.
