We report panchromatic light harvesting in hybrid TiO2/P3HT photovoltaic devices using a porphyrin dye that complements the light absorption of P3HT. The high short circuit photocurrent (12.1 mA cm-2) obtained is found to be due, in part, to Förster resonance energy transfer from the P3HT to the dye.
