Abstract
This letter reports our efforts to improve the power conversion efficiency (PCE) and the optical transparency of semitransparent poly(3-hexylthiophene) (P3HT):1-(3-methoxycarbonyl)-propyl-1-phenyl-(6,6)C60 (PCBM) based photovoltaic (PV) cells. Semitransparent P3HT:PCBM based solar cells were prepared based on parameters obtained by optical admittance analysis. The performance of structurally identical polymer PV cells made with a reflective calcium/silver cathode and a semitransparent Ca(10nm)∕Ag(10nm)/indium tin oxide cathode are compared. For semitransparent polymer PV cells with a 75nm thick active P3HT:PCBM blend layer, an average transmission of more than 30% was achieved with a high PCE of 1.7% under simulated AM1.5G illumination of 100mW∕cm2.Keywords
