Influence of Spray Pyrolysis Deposition Technique on the Performance and Stability of Polymer Solar Cells

In this research work, noteworthy progress has been achieved to fabricate stable inverted polymer solar cells using spray pyrolysis technique to deposit a thin film of ZnO as interfacial layer. A standard inverted polymer solar cells were fabricated by spin coating technique as reference devices. It was interesting to observe that the performance of the inverted polymer solar cells fabricated by ZnO-spray pyrolysis were quite similar to the reference samples fabricated by the ZnO-spin coating technique. However, the devices fabricated using the ZnO- spray pyrolysis showed higher current density as well as higher stability more than the ZnO- spin coating ones. Hence, this promising spray pyrolysis technique might be a breakthrough forward step for commercializing the inverted polymer solar cell based on mass production scale.
