“…This is due to the presence of MCMB, a type of carbon which is a light absorbing or trapping material. The absorption edge is similar in shape implying that the doping of MCMB does not alter the fundamental bond structure of the MEH-PPV [13].…”

Poly [2-methoxy, 5-(2-ethyl-hexyloxy)-p-phenylene-vinylene] (MEH-PPV) is a conjugated polymer that exhibit excellent luminescence properties in the visible spectrum. The fundamental absorption edge in the film is formed by the direct allowed transitions. In this work, free-standing films of MEH-PPV and MEH-PPV/MCMB were obtained by a solvent casting method. Mesocarbon Microbead (MCMB), a type of carbon, is added to the polymer producing composite films. The films were characterized by using the UV-Vis-NIR spectrophotometer. The film samples exhibited an absorption band in the red visible region. This is due to the electron transition between the non-localized bands. However, when MCMB is doped into the polymer matrix, the band absorption edge is red-shifted compared to that of the MEH-PPV pure film. Therefore, the optical band gaps of the composite films have decreased due to the presence of MCMB.

“…Several natural pigments [6,[8][9][10][11], synthesized dyes [4,[12][13][14], conjugated polymers [5,15] and low band gap semiconductor [16] have been identified as suitable sensitizers for fabricating NDP type solar cells. So far, only few semiconductor-semiconductor or semiconductor-polymer pairs have been identified to fabricate NDP type solar cells [6,17]. In this article, we report characteristics of CuSCN|ZnO hetro-junction fabricated by electrochemically at low temperature and a solid-state solar cell fabricated by sandwiching mercurochrome in between CuCNS and ZnO films.…”

Hybrid ZnO films were prepared via a single-step electrochemical process. Extraction of organic component from the hybrid films resulted tiny ZnO columns perpendicular to the substrate. A Semiconductor hetro Junction was prepared by depositing CuSCN on ZnO films. The maximum photocurrent of 0.36 mAcm-2 and photovoltage of 290 mV were observed for the solid-state cell fabricated by sandwiching organic dye mercurochrome in between ZnO and CuSCN films.

Organic semiconductor have been discovered in different application devices such as organic light emitting diodes (OLEDs).Poly [2-methoxy-5(2' -ethylhexyloxy)-1, 4phenylenevinylene), MEH-PPV widely used in this device because its ability to produce a good optical quality films. The MEH-PPV was prepared on glass substrate by spin coating method. The thin film was investigated with different concentration using toluene solvent. The scanning electron micrographs (SEM) and atomic force microscope (AFM) measurement revealed that at concentration of 5 mgml -1 showed uniformity and less aggregation on morphology and topology, respectively. The current-voltage (I-V) measurement revealed that the concentration of 5 mgml -1 showed high conductive and it is suitable for optoelectronic device.
