【摘要】：基于生物体光合作用的原理而研制的太阳能电池，因其成本低、环境友好，具有极大的开发潜力。本文以一种光合细菌—红假单胞菌为研究对象，对其培养、色素蛋白复合物的提取、色素蛋白敏化TiO2太阳能电池、以及光合细菌太阳能电池进行了研究。采用SMN培养基对光合细菌进行液体和固体接种培养，探讨了细菌的生长状况，研究了光合细菌在光学显微镜和透射电镜下的生物学形态。结果表明光合细菌经革兰氏染色呈红色，形状为杆形和弧形。采用超声波破碎和反复冻融相结合的方法从光合细菌中提取出了色素蛋白复合物的粗提物。结果表明，提取出的色素蛋白复合物在375nm、501nm、520nm、595nm、802nm和880nm处有吸收峰。将提取出的色素蛋白敏化TiO2太阳能电池，并对电池进行了光电性能测试。结果表明，，电池的开路电压、短路电流和内阻分别为279mV、10mA和27.9。对新型光合细菌太阳能电池的组装与电池性能进行了研究，探讨了阳极液中不同添加剂的加入对电池性能的影响，以及不同阳极材料对光合细菌太阳能电池的性能影响。结果表明，光合细菌太阳能电池在光照下可产生13μA的极化电流；葡萄糖和壳聚糖加入到电池阳极液中可使电池的光电流增大至21μA、27μA；蔗糖、蒽醌和醌氢醌加入到电池阳极液中对电池电流无显著作用。分别以TiO2电极、掺蒽醌石墨电极、掺醌氢醌石墨电极和双面石墨电极作为电池的工作电极，研究几种电极对电池性能的影响。结果表明，几种电极均有增大电池光电流的效果，其中尤以双面石墨电极促进效果最佳，光电流可增大至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.
