## Abstract The triplet exciton and polaron dynamics in phosphorescent dye (PtOEP) blended polymer (MEHโPPV) photovoltaic devices are investigated by quasiโsteadyโstate photoโinduced absorption (PIA) spectroscopy. According to the lowโtemperature PIA and photoluminescence (PL) results, the increase
