本研究工作係利用人工合成的紫質材料(porphyrin)，應用於平面異質接面(Planar heterojunction, PHJ) 結構的太陽能電池當中，證明紫質材料能與富勒烯衍生物(fullerene derivatives) 形成一個Donor / Acceptor異質接面，並量測到穩定的元件效率，更藉由改變主動層中搭配的受體材料，成功提升元件開路電壓與整體效率值。同時，探討蒸鍍製程與溶液製程之紫質成膜對薄膜性質的改變，以及元件表現上的差異。在電子施體端的研究中，使用一系列紫質衍生物，討論紫質分子的結構變化對元件電性造成的影響。

This study aims to employ synthetic porphyrins in organic planar heterojunction (PHJ) solar cells. The results suggest a well-defined Donor / Acceptor interface between porphyin and fullerene derivatives, which exhibit credible photovoltaic efficiency. Also, the improved open-circuit voltage (VOC) and device performance are observed through alternating acceptor components in the active layer. Comparative studies of thin-film properties and device characteristics are reported, in which the same porphyrin material is deposited using both solution-process and thermal deposition in vacuum.
In addition, a series of porphyrin derivatives is investigated as electron donor in porphyrin-base organic solar cells to get more insights into the correlations between molecular structures and device characteristics.
