【摘要】：基于生物體光合作用的原理而研制的太陽能電池，因其成本低、環(huán)境友好，具有極大的開發(fā)潛力。本文以一種光合細(xì)菌—紅假單胞菌為研究對象，對其培養(yǎng)、色素蛋白復(fù)合物的提取、色素蛋白敏化TiO2太陽能電池、以及光合細(xì)菌太陽能電池進行了研究。 采用SMN培養(yǎng)基對光合細(xì)菌進行液體和固體接種培養(yǎng)，探討了細(xì)菌的生長狀況，研究了光合細(xì)菌在光學(xué)顯微鏡和透射電鏡下的生物學(xué)形態(tài)。結(jié)果表明光合細(xì)菌經(jīng)革蘭氏染色呈紅色，形狀為桿形和弧形。 采用超聲波破碎和反復(fù)凍融相結(jié)合的方法從光合細(xì)菌中提取出了色素蛋白復(fù)合物的粗提物。結(jié)果表明，提取出的色素蛋白復(fù)合物在375nm、501nm、520nm、595nm、802nm和880nm處有吸收峰。將提取出的色素蛋白敏化TiO2太陽能電池，并對電池進行了光電性能測試。結(jié)果表明，，電池的開路電壓、短路電流和內(nèi)阻分別為279mV、10mA和27.9。 對新型光合細(xì)菌太陽能電池的組裝與電池性能進行了研究，探討了陽極液中不同添加劑的加入對電池性能的影響，以及不同陽極材料對光合細(xì)菌太陽能電池的性能影響。結(jié)果表明，光合細(xì)菌太陽能電池在光照下可產(chǎn)生13μA的極化電流；葡萄糖和殼聚糖加入到電池陽極液中可使電池的光電流增大至21μA、27μA；蔗糖、蒽醌和醌氫醌加入到電池陽極液中對電池電流無顯著作用。分別以TiO2電極、摻蒽醌石墨電極、摻醌氫醌石墨電極和雙面石墨電極作為電池的工作電極，研究幾種電極對電池性能的影響。結(jié)果表明，幾種電極均有增大電池光電流的效果，其中尤以雙面石墨電極促進效果最佳，光電流可增大至47.5μA。
[Abstract]:Solar cells, which are based on the principle of photosynthesis, have great potential for development because of their low cost and environmental friendliness. In this paper, a kind of photosynthetic bacteria, Rhodopomonas rubrum, was studied. Its culture, extraction of pigment protein complex, pigment protein-sensitized TiO2 solar cells and photosynthetic bacteria solar cells were studied. The liquid and solid inoculation of photosynthetic bacteria were carried out on SMN medium. The growth status of photosynthetic bacteria was studied and the biological morphology of photosynthetic bacteria under optical microscope and transmission electron microscope was studied. The results showed that the photosynthetic bacteria were red and arched by Gram staining. The crude extract of pigment protein complex was extracted from photosynthetic bacteria by ultrasonic crushing and repeated freezing and thawing. The results showed that the extracted pigment protein complex had an absorption peak at 5905 nm ~ (-1) ~ (-1) ~ (-1) nm ~ (-1) ~ (-1) ~ 520nm ~ (-1) ~ (-1) ~ 595 nm ~ (-1) 880nm. The pigment protein was extracted to sensitize the TiO2 solar cell and the photoelectric performance of the cell was tested. The results show that the open circuit voltage, short circuit current and internal resistance of the battery are 279mV 10mA and 27.9mA respectively. The assembly and performance of new photosynthetic bacteria solar cells were studied. The effects of different additives in anodic solution on the performance of solar cells and the effects of different anode materials on the performance of photosynthetic bacteria solar cells were discussed. The results showed that photosynthetic bacteria solar cells could produce a polarization current of 13 渭 A under light, glucose and chitosan could increase the photocurrent to 21 渭 A ~ (27 渭 A), sucrose, glucose and chitosan could increase the photocurrent to 21 渭 A ~ (27 渭 A). The addition of anthraquinone and hydroquinone into the anode solution has no significant effect on the cell current. TiO2 electrode, graphite electrode doped with anthraquinone, graphite electrode doped with quinone and graphite electrode with two sides were used as working electrodes respectively. The effects of several kinds of electrodes on the performance of the battery were studied. The results show that several kinds of electrodes have the effect of increasing the photocurrent of the battery, especially the double-side graphite electrode. The photocurrent can be increased to 47.5 渭 A.
