Transport and recombination dynamics studies of polymer/fullerene based solar cells

We have studied the electron/hole transport and recombination dynamics in blends of poly[2‐methoxy‐5‐(3′,7′‐dimethyloctyloxy)‐1,4‐phenylene vinylene], (MDMO‐PPV) and [6,6]‐phenyl‐C61‐butyric acid methyl ester (PCBM) at room temperature, as a function of laser excitation density and PCBM concentratio...

Description
Summary:We have studied the electron/hole transport and recombination dynamics in blends of poly[2‐methoxy‐5‐(3′,7′‐dimethyloctyloxy)‐1,4‐phenylene vinylene], (MDMO‐PPV) and [6,6]‐phenyl‐C61‐butyric acid methyl ester (PCBM) at room temperature, as a function of laser excitation density and PCBM concentration. The experimental results of these studies indicate the important role played by hole‐trap states in MDMO‐PPV. Electron and hole transport are not balanced within the blend. PCBM is a less disordered material than MDMO‐PPV and electron transport dominates the response of the solar cell device.
