In this paper we report on the vacuum thermal evaporation (VTE) of poly(3-hexyl)thiophene (P3HT) and a thiophene derivative octamer (OCT) on glassy substrates. The films obtained have been characterized using FT-IR and NMR techniques and, for OCT, UV–vis, XRD and cyclic voltammetry. Solar cells, obtained by simultaneous evaporation of the electron–donor (P3HT or OCT) and electron-acceptor (C 60 -fullerene) components, were examined by AFM and their efficiency was evaluated under simulated solar illumi- nation. With the oligomeric sample a power conversion efficiency of 1.21% was obtained: a value higher than that obtained with a device prepared with the same oligomer adopting the conventional coating systems used for building-up polymeric BHJ solar cells.

Abstract
In this paper we report on the vacuum thermal evaporation (VTE) of poly(3-hexyl)thiophene (P3HT) and a thiophene derivative octamer (OCT) on glassy substrates. The films obtained have been characterized using FT-IR and NMR techniques and, for OCT, UV–vis, XRD and cyclic voltammetry. Solar cells, obtained by simultaneous evaporation of the electron–donor (P3HT or OCT) and electron-acceptor (C 60 -fullerene) components, were examined by AFM and their efficiency was evaluated under simulated solar illumi- nation. With the oligomeric sample a power conversion efficiency of 1.21% was obtained: a value higher than that obtained with a device prepared with the same oligomer adopting the conventional coating systems used for building-up polymeric BHJ solar cells.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
