染料敏化太陽能電池及鈣鈦礦太陽能電池的研究發展

Research and Development Dye Sensitized Solar Cell and Perovskite Solar Cells

指導教授 : 王宏文

摘要


太陽能電池研究發展從1954年開始的第一代到現在已經發展到第三代染料敏化太陽能電池,然而由於有機染料的吸收係數低且吸光頻譜窄,不能有效獲取太陽光能量,使得其光電轉換效率無法超越第一代的傳統矽太陽能電池。為了彌補染料對於吸收太陽光頻譜的缺陷,量子點太陽能電池特別的光電特性即可改善這樣的問題。然而,量子點太陽能電池隨著使用量子點材料的不同,例如使用III-V族量子點太陽能電池會有接面上的電子電洞對易於復合,造成元件導電性下降;或是使用金屬硫化物材料會有化學不穩定性等議題待改善。為了克服量子點材料的這些問題,鉛鹵化物鈣鈦礦類型的敏化材料即被提出來做為解決方針。進而開啟了新型態的鈣鈦礦太陽能電池。 本文主要針對染料敏化太陽能電池與鈣鈦礦太陽能電池的發展與應用做探討。

Solar cell research and development from 1954 to the first generation is now in its third generation dye-sensitized solar cell, however, due to the low absorption coefficient of the organic dye and the absorbance spectrum narrow, can not effectively get solar energy, so that the photoelectric conversion efficiency can not go beyond the first generation of conventional silicon solar cells. To compensate for the dye absorption spectrum of sunlight defects, particularly a quantum dot solar cells can be improved photovoltaic characteristics such problems. However, quantum dot solar cells with quantum dots using different materials, for example thirty-five (III-V) family of quantum dot solar cells will be connected to the surface of the electron hole easy to complex, resulting in decreased conductive element; or metal sulfide materials have chemical instability and other issues to be improved. To overcome these problems the quantum dot material, perovskite type lead halide sensitized material i.e. propose to do to resolve the policy. And then opened a new type of perovskite solar cells. In this paper, the development and application of the dye-sensitized solar cells and solar cell perovskite do for discussion.
