本研究以PET-ITO導電塑膠基板成長氧化鋅奈米複合結構，應用於可撓式染料敏化太陽能電池。本研究以室溫化學浴法整合導電塑膠基板上之氧化鋅奈米仙人掌陣列及其及頂部顆粒層，作為氧化鋅奈米複合結構電極。其中氧化鋅奈米仙人掌陣列由室溫化學浴法成長於PET-ITO基板之氧化鋅奈米柱陣列所得。而氧化鋅顆粒層為塗佈於氧化鋅奈米仙人掌陣列頂部，繼以室溫化學浴法連接顆粒與奈米仙人掌，整合成為氧化鋅奈米複合結構。此導電塑膠基板成長之氧化鋅奈米複合結構製作之可撓式染料敏化太陽能電池，不需要高溫前處理與機械高壓就能達到5.24%之效率。藉由研究太陽能電池電子傳輸與再結合之行為可進一步確認，此簡易室溫化學浴法能夠將氧化鋅顆粒間互相連接，並整合氧化鋅奈米仙人掌陣列與氧化鋅顆粒，使電子能有效收集於此氧化鋅奈米複合結構之電極。
此外，為改善液態電解液於染料敏化太陽能電池中電解液漏液及揮發之問題，本研究亦利用10wt% PVDF-HFP高分子電解液製作以奈米仙人掌/片狀結構為光陽極之太陽能電池，其效率可達4.19%。於室溫下經由1000小時測試，仍具有約3.96%之效率。最後應用此膠態電解液於可撓式染料敏化太陽能電池，其效率可達約3.53%。

In this work, zinc oxide (ZnO) hierarchical nanostructures have been synthesized on PET-ITO plastic substrates for flexible dye-sensitized solar cells (DSSCs). A room-temperature (RT) chemical integration method is developed to construct ZnO nanoarchitectured anodes, composed of a ZnO nanocactus (NC) array and a top ZnO particle (ZnO TP) film. The ZnO NC array is derived from a nanowire (NW) array on PET-ITO substrate by RT chemical bath deposition (CBD). After drop casting ZnO particles on the top of ZnO NC array, another RTCBD is conducted for integrating the NC array and the TP film. Without high-temperature post-treatment and mechanical compression, a notable efficiency of 5.24% is simply achieved in the plastic-substrate ZnO DSSC. Dynamics of recombination and electron transport measurements indicate efficient electron collection in the ZnO nanoarchitectured anodes, confirming the inter-necking of the ZnO TP film and the connection of the particle film with underneath NC array by the facile RTCBD method.
To solve the leakage and evaporation of the liquid electrolyte in DSSC, gel-state DSSC with ZnO nanocactus/nanosheet anode was fabrication in this work. The power conversion efficiency of 4.19% is achieved by using 10wt% PVDF-HFP polymer electrolyte. After 1000 h test under 25°C, the efficiency of the gel-state DSSC can retain 3.96%. Finally, a gel-state flexible DSSC was fabricated. An efficiency of 3.53% is obtained.
