Abstract
The properties of photovoltaic cells containing an MEH-PPV composition with palladium(II) meso-tetra(benzo-15-crown-5)porphyrinate as an electron-conduction layer and copper(II) phthalocyanine as a hole transport layer were studied. The influence of the environment and a top-electrode metal on the operation efficiency was also examined. It was found that oxygen at the fabrication steps affects in different manners the formation of open-circuit voltage and the performance of the device. A certain correlation between the properties of electrodes and the photoelectromotive force was established. The highest conversion efficiency of 0.02 electrons per incident photon was obtained for samples that additionally contained an amorphous selenium layer applied over the aforementioned conducting layers.
