Abstract
This study primarily employed poly-(3-hexylthiophene) (P3HT): [6,6]-phenyl C61-butyric acid methyl ester (PC61BM) solvent to produce single-layer organic photovoltaic (OPV) cell of single-layer bulk heterojunction (BHJ). The OPV cell structure is ITO/PEDOT:PSS/P3HT:PC61BM/LiF/Al. In the process, we examined the optoelectronic properties of producing P3HT:PC61BM single-layer OPV cells in various thicknesses of active layer, temperatures, and times of thermal pre- and post-annealing. The results showed that the maximum conversion efficiency (ηp) of single-layer OPV cells increased in crystal level of P3HT molecule from low temperature to high temperature process and effective contact area between active layer and metal cathode of device. Thus the ηp value of cells can reach 4.58% after pre- and post-annealing.
