16 November 2010Effect of buffer layers on the performance of P3HT:PCBM solar cells
We have studied the effect of buffer layers on the performance of poly(3-hexylthiophene-2,5-diy1) (P3HT):C61-butyric
acid methyl ester (PCBM) bulk heterojunction solar cells. We proved that depositing a thin pentacene layer between
metal cathode and P3HT: PCBM blend and introducing a thin P3HT layer between ITO and photoactive layer, would
improve the power conversion efficiency of polymer bulk heterojunction solar cells when compared with the cells
without the buffer layers. In the study, the buffer layers increased short circuit density (Jsc) and open circuit voltage
(Voc) under the illumination by white light from a solar simulator with an incident intensity of 100mW/cm2. The thin
pentacene layer as a cathode buffer layer modifying the contact between the active layer and the cathode, the thin layer
of P3HT as a anode buffer layer enhancing the electron blocking ability were responsible for the improvement on the
performance of photovoltaic device.
