- Abstract
- We demonstrate hybrid tandem photovoltaic devices with a transparent conductive interconnecting recombination layer. The series-connected hybrid tandem photovoltaic devices were developed by combining hydrogenated amorphous silicon (a-Si:H) and polymer-based organic photovoltaics (OPVs). In. order to enhance the interfacial connection between the subcells, we employed highly transparent and conductive indium tin oxide (ITO) thin layer. By using the ITO interconnecting layer, the power conversion efficiency of the hybrid tandem solar cell was enhanced from 1.0% (V-OC = 1.041 V, J(SC) = 2.97 mA/cm(2), FF = 32.3%) to 2.6%. (V-OC = 1.336 V, J(SC) = 4.65 mA/cm(2), FF = 41.98%) due to the eliminated interfacial series resistance.
