Photovoltaic Properties of Rare Earth Organic Electroluminescent Devices

摘要

Photovoltaic effects of rare earth organic electroluminescent devices(OELD), ITO/TPD/Gd(DBM) 3 bath, were described. Double OEL devices with Gd complex indicated considerable photovoltaic properties. About 20 μA·cm -2 of maximum short current ( I sc ) and 2 2 V of maximum voltage ( V oc ) of the photovolotaic cell with the rare earth complex under illumination UV lamp with 365 nm were achieved. Although the most sensitive response of it is at UV region, V oc larger than 1 5 V under solar illumination can also be observed. Under UV light illumination of 367 nm, V oc =844 mV, I sc =2 1 μA·cm -2 and 4% of energy transfer efficiency were measured.
