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.展开更多

Compared the results with both the old analytical model and the full band model, it is found that they are possibly in reasonable agreement with the full band method and we can improve the calculation precision. Another important work is to reduce the programme computation time using the method of data fitting scattering rate curves.展开更多
