Abstract :
Inverted organic solar cells (IOSCs) have been fabricated and characterized. The blend of poly(3-hexythiophene)(P3HT) and [6,6]-phenyl C61-butyric acid methyl ester(PCBM) is adopted as an active material. The anode is formed by Ag nanoparticles, which is fabricated using a Pasteur burette to drop by the titration. The solution-processed cooper phthalocyanine (CuPc) is used as a hole transporting layer (HTL) onto the poly (3,4ethylenedioxythiophene) : poly (sterene sulfonate) (PEDOT:PSS) for realizing to fabricate IOSCs by an all-solution process. An IOSC under the optimized structure of ITO/ZnO/P3HT:PCBM/PEDOT:PSS/CuPc/Ag exhibits open circuit voltage (Voc) of 0.557 V, short circuit current density (Jsc) of 6.344 mA/cm2F.F. of 41.53% and PCE of 1.47% at AM 1.5G of 100 mW/cm2. Solution process is feasible for low-cost, large-area solar energy applications.
