摘要: 隨著太陽能在科技與環境革新中成為先鋒,商業化太陽能發電方式越也越受到企業 經營者,以及消費者關注。擷取太陽能有許多不同種的方式,瞭解箇中的差異,對欲投 資者具重要意義。矽太陽能電池與有機太陽能電池,是光伏打電池中的兩大主流型式— 談及太陽能電池時,各種型式的成本、效率及耐用性都是須納入考量的重要因素。 從另一個角度來看,將熱能轉換為電能已經伴隨我們將近百年,試想如果能有效地 將四周的廢熱或太陽熱能轉換為電能。熱電轉換在不久的未來勢必會發展成具規模的產 業。本計畫旨在,新穎有機/無機異質介面應用於日常生活之太陽能電池基料及元件的研 究,及以無機奈米線之熱電/熱釋電性質開發新型發電機。 我們將以研究有機/矽介面性質中獲得的成果,應用到雙異質結構有機/矽太陽能電 池,利用由奈米科技中心及交通大學應用化學所研製的三硒化二銻單根奈米線的特性, 並集中大量資源,投入發展有機/無機太陽能電池與熱電/熱釋電元件裝置,也以我們自 己製作與其他單位所提供的奈米線,來分析其特性及元件的效能,並設計適當的模型, 描述奈米結構中,高分子/矽介面性質及熱電/熱釋電效應。最後,我們要製作出具市場 價值的新穎有機/無機太陽能電池和熱電/熱釋電元件裝置,作為商品化的奠基。 將太陽能及熱能轉換為電能,這種幾乎零汙染的替代能源科技,是相當重要的。本 計畫中,數個關鍵技術之目標及操作方針如下:  研究有機/無機介面的性質及能帶並優化,以達開發新穎光伏打電池之目的  高分子使用於多晶及單晶矽雙異質介面太陽能電池之展示  瞭解在有機/無機太陽能電池中,光激發電子電洞之動力行為  發展可行的量測技術,用以研究單根奈米線之熱電傳輸行為  在單根三硒化二銻奈米線中塞貝克效應和熱電轉換之展示  在單根三硒化二銻奈米線中光反應和熱釋電轉換之展示  以三硒化二銻為基礎,製作熱電/熱釋電元件裝置之發展
As solar energy becomes a front-runner in the technological and environmental revolution, a growing interest in commercial solar power is becoming a common concern for business owners and individual consumers. There are several different ways to harness the sun's energy and knowing the difference among these methods is significant for possible investors. Two of the most common forms of photovoltaics are silicon solar cells and organic solar cells--the cost, efficiency and durability of each form are all considerable factors when thinking about going solar. On the other end of the spectrum, the ability to convert heat energy into electrical energy has been with us for almost 100 years. Imagine the ability to efficiently harness the waste heat or solar thermal energy that constantly surrounds us and converts them into electricity. The conversion of thermal energy into useful electrical energy should develop into a large industry in the near future. This project aims to conduct basic material and device studies of novel organic/inorganic heterostructure solar cells for terrestrial applications, as well as using inorganic nanowires for thermoelectric/pyroelectric energy generation. We are going to apply all the knowledge acquired on properties of the organic/Si interface, on fabrication of double heterostructure organic/Si of solar cells, and on characterization of Sb2Se3 single nanowires in the Department of Applied Chemistry and Center for Nano Science and Technology of NCTU and to focused significant resources on developing capabilities for the fabrication of organic/inorganic solar cells and thermoelectric/pyroelectric devices, on characterization on these samples and on samples obtained from other sources, on analyzing the results and device performance, and on developing appropriate model for polymer/Si interface and thermoelectric/pyroelectric effect in nanostructures. Finally, we are going to lay the foundation for making market-value novel organic/inorganic solar cells and thermoelectric/pyroelectric devices for industrial production. Conversion of solar and thermal energy into electric energy is the most important, virtually free of pollution technology for alternative energy resources. Some key technical goals and operational features of our plan are: • Development and adjustment to photovoltaic purposes novel organic/inorganic interface properties and band structures • Demonstration of double heterostructure photovoltaic cells of polymers on poly- and crystalline Si substrates • Understanding dynamics of photoexcited electrons and holes in organic/inorganic photovoltaic cells • Development of viable measurement technology to study the electrical and thermal transport behavior in single nanowires • Demonstration of Seebeck effect and thermoelectric conversion in single Sb2Se3 nanowires • Demonstration of photoresponse and pyroelectric conversion in single Sb2Se3 nanowires • Development of thermoelectric/pyroelectric devices based on Sb2Se3 nanowires
