Composite films of P3HT/PCBM-(poly[3-2,5-diyl]/[6,6]-phenyl C61 butyric acid methyl ester) are widely used as an active layer in plastic solar cells. We have studied the influence of thermal annealing on nano-structural and optical properties of thin

The photovoltaic action of plastic solar cells based on P3HT/PCBM- (poly[3-hexylthiophene-2,5-diyl]/[6,6]-phenyl C 61 butyric acid methyl ester)-composites depends strongly on structure of the active layer. In this work, the impact of P3HT-crystallin

We investigate thin poly(3-hexylthiophene-2,5-diyl)/[6,6]-phenyl C61 butyric acid methyl ester (P3HT/PCBM) films, which are widely used as active layers in plastic solar cells. Their structural properties are studied by grazing-incidence X-ray diffra

Poly(3-octylthiophene) (P3OT) is a promising candidate for plastic solar cells. We have determined the anisotropic dielectric function (DF) of thin spin-coated and drop-cast P3OT-films deposited on Si and glass substrates from both near-normal reflec
