In the
present work, the photoactive layer of
blended of poly (3- hexylthiophene) (P3HT) and [6,6]-phenyl C61-butyric acid
methylester (PCBM) based on BHJ concept was used to produce PCS. The
configuration of Ag/MoO3/ P3HT:PCBM/ZnO/ITO/Glass was used. Confocal Raman measurements
and Atomic Force Microscope (AFM) were carried out at room temperature to
figure out the morphology of PSC layers. Raman spectra shown that the
strongest peak for ZnO thin film was at 437 cm−1 and the most intensive Raman peak of P3HT:PCBM
photoactive layer was observed at 1442 cm-1. Moreover,
other Raman peaks for both ZnO and P3HT were
clearly observed in the Raman spectroscopy results. The photovoltaic (PV) performance of PCS was evaluated
by using the current density-voltage (J-V) measurement under AM 1.5
illumination. The power conversion
efficiencies (PCE) of PSC was measured as 3.74 %. Additionally, the device exhibited a
short-circuit current (JSC)) of 9.95 mA/cm2, open-circuit
voltage (VOC) of 0.57 V and fill factor (FF) of 66%.
