Polyacetylene thin film photovoltaic devices

2014 Photovoltaic devices have been obtained by a direct polymerization of undoped (or p-type doped) thin film (CH)x layer onto a polycrystalline cadmium sulfide film. The morphology of the contact is observed by S.E.M. microscopy. The electrical characteristics of this device are studied in the dark or under illumination. The main result, at AM1, 100 mW/cm2 with doped (CH)x correspond to 0.5 p...

Photovoltaic Effect of Acriflavine in Collodion Film

cesses in photochemical behaviours o f the dye. Th e observed photopotential in aqueous acriflavine solution is positive or negative against the dark electrode, depending on pH . The positive sign implys that the photoreduction of dye is more predominant than the photooxidation. The negative sign is obtained when the photooxidation is the predominant reaction. Using the electrode coated directl...

Simple Photovoltaic Device Based on Multiwall Carbon Nanotube/Silicon Heterojunction

Multiwall carbon nanotubes (MWCNTs) are grown via chemical vapour deposition method directly on a stainless steel substrate. Raman spectroscopy and transmission electron microscopy are the techniques chosen to characterize the structure of the synthesized carbon nanotubes: few structural defects are detected. After their removal from the stainless steel substrate, the as-grown MWCNTs are then a...
