【摘要】：螺旋藻生物太陽能電池能夠捕獲太陽能并產(chǎn)生電能，實(shí)現(xiàn)了CO2的零排放，具有清潔可循環(huán)利用和產(chǎn)能高效等優(yōu)點(diǎn)，受到越來越廣泛的關(guān)注。本文對螺旋藻的培養(yǎng)及色素蛋白的提取，螺旋藻生物太陽能電池的構(gòu)建和電池陽極材料的選擇進(jìn)行了研究。 本文采用S氏培養(yǎng)基對螺旋藻進(jìn)行培養(yǎng)，通過對螺旋藻進(jìn)行長期觀察并繪制生長曲線對螺旋藻的生長狀況進(jìn)行分析。從螺旋藻中提取藻膽蛋白與方酸菁染料復(fù)合,敏化納米晶TiO2光電陽極構(gòu)建染料敏化太陽能電池，并研究了電池的光電特性。 采用螺旋藻作為新型光敏劑構(gòu)建螺旋藻生物太陽能電池，對電池的結(jié)構(gòu)進(jìn)行了優(yōu)化并對其產(chǎn)電性能進(jìn)行了分析。螺旋藻具有光電轉(zhuǎn)換能力,并且在電池中能夠產(chǎn)生70μA光電流,與此同時(shí),考察了在電池陽極室中分別添加葡萄糖、蔗糖和殼聚糖等糖類,可以使電池的最大電流分別增長了80μA,100μA和84μA,添加蔗糖后可以使電池的最大功率密度提高到63mW/m2。 本文還對螺旋藻生物太陽能電池陽極材料的選擇進(jìn)行了研究，設(shè)計(jì)制作了蒽醌石墨電極、醌氫醌石墨電極、雙面石墨電極、納米晶TiO2電極以及用Cy3敏化后的納米晶TiO2電極，組裝成螺旋藻生物太陽能電池后，，光電流分別提高了61μA、50μA、154μA、25μA和43μA。雙面石墨電極可以明顯提高光電流，選擇最適合的螺旋藻生物太陽能電池陽極不僅可以提高電池的光電轉(zhuǎn)化效率，還可以降低電池內(nèi)阻，提高電池的輸出功率。
[Abstract]:Spirulina biological solar cells can capture solar energy and generate electric energy, achieve zero emission of CO2, and have the advantages of clean recycling and efficient production capacity. In this paper, the culture of Spirulina and extraction of pigment protein, the construction of spirulina biological solar cells and the selection of anode materials were studied. In this paper, Spirulina platensis was cultured in S's medium. Through long-term observation of Spirulina platensis and drawing the growth curve to analyze the growth status of Spirulina spirulina and extract phycobilis protein from Spirulina platensis and compound with squaric acid cyanine dye. Dye-sensitized solar cells were constructed by sensitized nanocrystalline TiO2 photoanode and their photoelectric characteristics were studied. Spirulina was used as a new type of Guang Min to construct spirulina biological solar cell. The structure of the cell was optimized and its electrical properties were analyzed. Spirulina had the ability of photoelectric conversion. At the same time, the addition of glucose, sucrose and chitosan in the anode cell of the battery was investigated. The maximum current of the battery was increased by 80 渭 A 100 渭 A and 84 渭 A, respectively, and the maximum power density of the battery was increased to 63 MW / m ~ (2) after adding sucrose. The selection of anode materials for spirulina biological solar cells was also studied in this paper. The anthraquinone graphite electrode, quinone hydroquinone graphite electrode and double side graphite electrode were designed and fabricated. Nanocrystalline TiO2 electrode and nanocrystalline TiO2 electrode sensitized by Cy3 were assembled into spirulina biological solar cells, the photocurrent increased by 61 渭 A ~ (50) 渭 A ~ (10) 渭 A ~ (154) 渭 A. 25 渭 A and 43 渭 A. Double-sided graphite electrodes can significantly increase photocurrent. Selecting the most suitable anode of spirulina biological solar cell can not only improve the photoconversion efficiency of the cell, but also reduce the internal resistance of the cell. Increase the output power of the battery.
