Enhancement of the Power Conversion Efficiency by Simple Heat-treatment of ZnO in Organic Photovoltaic Device
- Abstract
- Simple method for ZnO nano-ripple structure at low temperature was developed in this research, and a power conversion efficiency (PCE) of ~8.5% in inverted organic photovoltaic(OPV) device was achieved. In these days, ZnO nano-ripple structure is widely used in inverted OPV due to structure aspect. However, further improvement is indeed needed in surface between ZnO and active polymer layer due to the presence of contact barrier. ZnO nano-ripple film was made by simple technique. Structural strength and lower energy barrier of the ZnO nano-ripple were verified. Also we applied this material at flexible substrate to fabricate OPV device. The flexible device synthesized by simple method showed PCE of ~5.5%.
