AbstractWe have investigated the effects of thermal annealing before and after cathode deposition on poly(3-hexylthiophene)(P3HT)/[6,6]-phenyl C61-butyric acid methyl ester (PCBM) blend photovoltaic cells with different cathode buffer layers. The introduction of cathode buffer layer such as lithium fluoride (LiF) and calcium oxide (CaO) in pre-annealing cells can increase the open-circuit voltage (V(oc)) and the power conversion efficiency (PCE). Post thermal annealing after cathode deposition further enhanced the PCE of the cells with LiF/Al cathode. whereas the performance of the cell with CaO/Al cathode is decreased. It is found that the V(oc), and PCE can be largely enhanced when the post-annealed cell with Ca/Al cathode is exposed in air. This may attribute to the formation of CaO buffer layer, which favors increasing shunt resistance and V(oc). Finally, a PCE of 4.60% is calculated under AM1.5G solar illumination at 100 mW/cm(2).
