Two different kinds of novel 3D organic/inorganic hybrid photovoltaic devices which are (a) extremely thin absorber (ETA) solar cell based on the composite nanostructure.(b) Polymer/tree-like nanostructure 3D photovoltaic devices are proposed for investigation. . We would like to set up the in situ measurements for the studies of charge separation and transport mechanisms in the 3D photovoltaic devices through the 2-D mapping technique for photocurrent, PL intensity, PL lifetime and carrier mobility. The mapping image of optical and electric properties can be compared directly with the morphology from AFM images in the hybrid materials. The setup consists of a confocal microscope with the XY-scanning piezo stage integrated with our previous setups of standalone time-resolved PL system, photocurrent measurement system and time-of-flight mobility measurement systems.太陽能電池共軛高分子奈米柱電荷分離及傳導Organic/inorganic photovoltaic devicescharge separationcharge transport
