【 摘 要 】

Bio-photovoltaic is one of the energy-transfer technology that uses oxygenic photoautotrophic organisms to harvest light energy and generate electricity. The aerobic phototropic organisms such as blue-green algae primarily absorb solar energy in visible light areas (400-700 nm). The design of a bio-photovoltaic prototype cell can be constructed using electrodes and Cyanobacteria put inside a plastic container. When the cell is irradiated the photosynthetic reactions will run and produce free electrons. Based on a previous result it is possible to put the cathodes inside the chamber or outside the chamber. In this research, the anode was variated using copper, stainless steel, and zinc. For the measurement while all of the electrodes are in the chamber the efficiency value of each metal is 0.094%; 0.3475%; 4.1026% with the fill factor value of each metal is 0.5719; 0.4204; 0.5776. On the other hand, when one of the electrodes is outside the chamber efficiency value of each metal is 0.0058%; 0.4949%; 1.3013% and the fill factor value of each metal is 0.5559; 0.3519; 0.4564.
