Abstract:

Article Preview

In order to more improve the performance of the existing P3HT:C60 polymer photovoltaic cells, we adopted soluble C70 insteade of C60. The absorption spectra of soluble C70 showed a significant increase of visible range absorption, resulting in the enhanced photocurrent. To optimize the device fabrication, we controlled the solvent, concentration of polymer solution and the thickness of photo-active layer. The best power conversion efficiency obtained in our P3HT:C70 photovoltaic cells was about 3.0 % under AM 1.5G condition.
