Abstract
T
he electrical, optical, and structural properties of indium free Al doped ZnO (AZO)/Ag/AZO triple layer electrodes deposited
by r oom temperature sputtering without post treatments were investigated . T he conductivity of the AZO/Ag/AZO triple layer
electrodes grown on glass substrates can be improved by the insertion of an Ag layer The best figure of merit value (Φ TC )
was 39.9×10 3 Ω 1 for the AZO/Ag/AZO electrodes with 8 nm thick Ag layer. Moreover, bulk heterojunction organic polymer
solar cell s based on the AZO/Ag/AZO triple layer and AZO single layer electrodes were fabricated for a comparative study.
The polymer solar cells using AZO/Ag/AZO transparent electrodes exhibited higher performance than the cell using pure
AZO electrodes, due to much lower sheet resistance of the electrode. This implie s that indium free AZO/Ag/AZO triple layer
electrodes are a n appropriate transparent ele ctrode for low cost and low temperature processing organic photovoltaics..
