Investigation onI-Vfor Different Heating Temperatures of Nanocomposited MEH-PPV:CNTs Organic Solar Cells

摘要

This paper discussed the effect of different thermal evaporation treatments for nanocomposited MEH-PPV:CNTs thin films towards the performance of organic solar cells. The configuration of the organic solar cells is ITO/MEH-PPV:CNTs/Au. The heating temperature was varied from, as deposited,50°C,75°C, and100°C. From the results, we observed that the efficiency increase slightly before decreasing back at100°C. The highest efficiency was solar cells heated at75°C with efficiency 0.001% which is supported by theI-Vcharacteristics and also by the absorption spectra.
