文摘

We demonstrate semi-transparent organic inverted photovoltaic cells integrating a transparent anode based on two different transparent materials poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS Clevios PH1000) and PH1000/Tungsten Oxide (WO_x). Transparency of the device employing PH1000/WO_x over the visible region is 40 % , which is comparable to those without WO_x. The performance of the semi-transparent device exhibited the short-circuit current density (J_sc) of 6.72 mA/cm², filling factor (FF) of 55.8 % along with 0.65 V open-circuit voltage, leading to power conversion efficiency (PCE) of about 2.45 % . It is found that the device employing PH1000/WO_x exhibited better stability compared to the cells with only PH1000 cathode.
