Abstract

A study about fluorescence phenomena in hybrid donor-acceptor interfaces based on electrodeposited zinc oxide (e-ZnO) having different architectures is performed. In particular ITO/ZnO/P3HT and ITO/ZnO/P3HT:PCBM are investigated and their photoluminescence responses are compared with those of ITO/P3HT and ITO/P3HT:PCBM. As expected, ITO/ZnO/P3HT:PCBM and ITO/P3HT:PCBM present higher exciton quenching than ITO/ZnO/P3HT and ITO/P3HT respectively. Furthermore, the hybrid configuration ITO/ZnO/P3HT:PCBM displays a higher quenching percentage in a wider wavelength range than ITO/P3HT:PCBM, indicating a better photo-induced charge separation in e-ZnO based hybrid devices.
