| Summary: | 碩士 === 元智大學 === 光電工程學系 === 105 === In chapter I, we introduce the developed history and basic principle of organic solar cell (OPV). In addition, the recent development of OPV also included. Chapter II provides experimental setup, processes, methods and measurement methods.
In chapter III, three complementary organic materials ClAlPc, TAPC, SnNcCl2 were employed to assemble a multiple reflection system. To exhaust the incident light energy, the efficiency in various sequences by three OPV types was calculated. The most efficient case, TAPC:C70—ClAlPc:C70—SnNcCl2:C70, exhibited a high efficiency of 6.52%. In the contrast, the lowest efficient case, SnNcCl2:C70—ClAlPc:C70—TAPC:C70, showed a low efficiency of 2.87.
In chapter IV, we utilized four donor-donor-acceptor (D-A-A) configurations molecules, DTCTiFBT, DTCToFBT, DTCPiFBT, DTCPoFBT, (from Prof. Wong of Chemistry Department, National Taiwan Universtiy) as donor materials in active layer of organic solar cell. To optimized the device structure, their highest power conversion efficiencies were 3.20%, 3.42%, 3.59%, 3.56% for device with DTCTiFBT, DTCToFBT, DTCPiFBT, DTCPoFBT, respectively.
In the further, another four donor–donor–acceptor (D–A–A) molecules, DTCTiPTD, DTCToPTD, DTCPiPTD, DTCPoPTD, as donor materials of organic solar cell. To optimize device structure, the highest power conversion efficiencies are 7.53%, 5.09%, 6.45%, 6.29% for device with DTCTiPTD, DTCToPTD, DTCPiPTD and DTCPoPTD, respectively.
