摘要：本計劃主要是要探討在有機無機混成之太陽能電池中，電荷分離與傳導機制之研究。我們主要探討兩種太陽能電池結構。一種為極薄吸收型(extremely thin absorber) 太陽能電池，利用n-ZnO/P3HT/p-CuSCN 之奈米結構。另一種為樹狀之有機無機混成之太陽能電池結構，增加電荷分離效率及傳導路徑。我們將整合時間解析之螢光光譜系統、光電流量測系統、電荷遷移率量測系統於一套可作二維Mapping之共焦顯微鏡。所量測之光電特性可與原子力顯微鏡之表面morphology作對應。使我們能夠對有機無機混成之太陽能電池中之電荷分離與傳導機制，作深入之探討，進而提高其光電轉換效率。
Abstract: In this project, fundamental charge separation and transport mechanisms in the 3D photovoltaic devices based on hybrid materials will be investigated. Two different kinds of novel 3D organic/inorganic hybrid photovoltaic devices which are (a) extremely thin absorber (ETA) solar cell based on the n-ZnO/P3HT/p-CuSCN 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.
