Effect of metal contact on MEH-PPV organic solar cells application / Hudaliyana Ghazali

This paper focuses on the characterization of electrical, physical and optical properties. The active layer of the sample that has been used is the mixture of polymer MEH-PPV and THF. The active layer was deposited on top of the substrate using the spin coating technique. Then, the metal contacts were deposited. Type of metal contacts that involved in this experiment are Silver (Ag), Gold (Au) and Platinum (Pt). Another variable that is varied is the number of active layers on a substrate. Besides the effect of metal contact on MEH-PPV, this research is also done to investigate whether the thickness of the polymer will affect the optimization of OSC properties. The sample C which is the sample with 5 number of time of thin film being deposited has the best optical and physical properties. Metal contact of Ag, Au and Pt were deposited on these samples and it was observed that Ag portrays the best photoconductivity.
