✦ Synopsis
Using the delayed collection field techmque we measured the slope to intercept ratlo of the photogeneration quantum etkency m p-metal-free phthalocyamne At short delay times between pulsed laser lllurnmat~on and the application of the collection field slope to intercept ratlo IS slgmficantly smaller than the value predicted by the Onsager theory of geminate recombmatlon At longer delay times, exceeding about 200 ms, the slope to mtercept ratlo reaches the theoretIca value mchcatmg that the time evolution of geminate recombmatlon IS slgmficantly slowed down by traps At higher fields the tamer generanon IS dommated by the field modulated yield of the gemmate pairs
