摘要: | 近年來地球暖化以及能源問題逐漸被重視,大量的碳元素被儲存在石化燃料中,近年來人口成長及能源大量的運用,將這一些碳元素再一次地釋放到大氣中,被認為是可能造成全球暖化的因素之一。在能源方面開始尋找替代石化燃料的解決方案:風力、水力、潮汐、地熱以及太陽能等等。植物光合作用所使用的蛋白質複合體光系統一(Photosystem I, PSI)與光系統二(Photosystem II, PSII)具有接近100%的光電轉換效率。本論文採用植物擷取光能蛋白質光系統二(Photosystem II, PSII)作為擷取光能的材料使用,為了達成增加元件使用壽命的目的,本文針對元件結構上做兩個方向的研究:溶液狀態PSII(Solution-State PSII)元件與乾燥狀態PSII(Solid-State PSII)元件。
為了驗證本論文欲達到的目的,兩種元件均製作完成且經過實驗上的驗證。溶液狀態PSII(Solution-State PSII)元件能針對不同光強度與閃爍頻率變化上產生與過去文獻相對應的光電流反應;進而驗證乾燥狀態PSII(Solid-State PSII)元件也能在不同光強度與閃爍頻率上產生光電流反應。由這兩種類型元件的結果可知,本論文的實驗結果證實了植物擷取光能蛋白質光系統二(Photosystem II, PSII)具有成為擷取光能元件材料的潛力。 In recent years, the global warming and energy problems have gradually taken seriously by the people. A huge number of carbon atoms were stored in fossil fuels in the past; a large number of population growth and energy use in recent years, these elements of carbon once again are released into the atmosphere, which are considered as one of the factors causing global warming. In the energy issues, people began to looking for alternative solutions to fossil fuels: wind, hydro, tidal, geothermal and solar energy and so on. Plant photosynthesis protein complexes, such as Photosystem I(PSI) and Photosystem II(PSII), their photoelectric conversion efficiency are nearly 100%. In this paper, using PSII extracted from spinach which can capture light energy, and we trying to increase stability of the devices. In the paper, we design two kinds of device structure to use the PSII: the solution-state PSII device and solid-state PSII device. In order to verify the purpose of this paper, two kinds of device structure are made and measured. Solution-state PSII device can generate proportional photocurrent to different light intensity and different on/off frequency light source; further verify the solid-state PSII device can also generate photocurrent in a different light intensity and flashing frequency light source. Both types of devices by the results of our experimental are confirm that PSII is a potential material to capture light energy. |
