Photocurrent (PC) and current-voltage measurements were taken on MEH-PPV [poly(2-methoxy-5-(2′-ethyl-hexyloxy)-paraphenylene vinylene] in an as-made photocell, ITO / MEH-PPV (265 nm) / Al, in the photocell under ambient air, under a mixture of oxygen + nitrogen, and in vacuum after annealing. We discuss the different spectral responses and current-voltage characteristics obtained for the different atmospheres.
