摘要：
In this research, we examined the influence of platinum octaethylporphyrin (PtOEP) concentration on the photovoltaic and impedance spectroscopy of P3HT:PCBM solar cells. Through optimizing the concentration of PtOEP in the blend, the average power conversion efficiency of P3HT:PCBM solar cells was raised from 3.06 to 3.61%, when milligram of PtOEP was added to the blend. According to the impedance spectroscopy, the low concentration of PtOEP significantly increases the recombination process, simultaneously increasing the diffusion coefficient (D) and charge-carrier mobility (mu). These findings suggest that the incorporation of low doses of PtOEP into P3HT:PCBM blends will be a practical method for achieving the high efficiency of polymer solar cells.
