Interfacial analysis of the rrP3HT samples spincoated on a glass substrate was studied in detail using transmission electron microscopy (TEM) and SEM measurements. Very homogeneous and smooth polymer (P3HT and PEDOT:PSS) layers are observed on the glass substrate. The ITO surface shows a surface roughness, with a layer of about 15 nm. Structural characteristics of the polymer blends were studied using Raman spectroscopy and photoluminescence (PL). The complete reduction of PL of P3HT after mixing with C60 in a 1:1 wt.% indicates an effective charge transfer from P3HT to C60. Thermo-gravimetric analysis showed that the commercially bought materials are of high purity.
