“…It is in absolute agreement of the electrolyte concentration used in the literature to P3ATs synthesis. Recently, Santana and coworkers [10,12,28,29] have shown that the P3ATs synthesis is possible using diferent supporting electrolytes, solvents and thicknesses. Therefore, it was possible to correlate the growth conditions of the electrochemical synthesis and optical properties to produce polymer ilms with possible application in optoelectronic devices.…”

Poly(3-alkylthiophene) (P3ATs) have been extensively used in photovoltaic devices such as a p-type organic Semiconductors. However, several electronic properties of P3ATs present energy transfer inter-and intra-chains that have direct consequences on the performance of optoelectronic devices. Traditionally electrochemical techniques, such as cyclic voltammetry, chronoamperometry and chronocoulometry, have been applied to process polymer thin ilms and unconventional spectroscopy techniques are used to characterize the electronic properties. In the present work, we used an innovative technique called ellipsometry emission to investigate the optical properties of P3AT ilms. We propose a new approach to study the electrochemical synthesize and unintentional doping processes of polymeric systems. We showed a strong correlation between the electrochemical synthesis and the optical properties controlling the ilm growth conditions for P3ATs. The results obtained in the present study can be potentially utilized for applications in organic devices, mainly in photovoltaic cells when the ilm deposition and the optical properties control are relevant.
