The Effect of LiF Buffer Layer on The Performance of Polymer Solar Cell based on Synthesis MEH- PPV

One of effective ways to enhance electric performances of organic solar cells is use ofelectrode buffer layer. And LiF is the widest materials, which is used as a cathode buffer layer. In thispaper, organic solar cells based onsynthesis MEH- PPV and C60 are fabricated. And the LiF cathodebuffer layer is studied. The insertion of nano layers of LiF under the negative metal electrode Al of bulkheterojunction solar cells significantly enhances the fill factor. Compared to devices without the LiFinterfacial layer, the Jsc increase from-0.08 to -0.22 mA/cm2.
