A Novel Photosynthetic Bacteria Solar Cell

Article Preview

Abstract:

In this paper, a novel photosynthetic bacteria solar cell with Rhodopseudomonas as the electricity generation bacteria was designed and prepared, and photo current changing with the time of the cell was investigated by testing current-time(i-t) curve under alternating light and dark. The results showed that the maximum photo current of the cell could be 13 μA. The influence of glucose, sucrose, chitosan, anthraquinone and hydroquinone on the photo current was investigated. The results indicated that glucose and chitosan made the photo current of solar cell increased about 21 μA and 27 μA, respectively; but sucrose, anthraquinone or hydroquinone had not such effect. It illustrated that photo electrons could be emitted by Rhodopseudomonas and were transmitted to the anode of the cell in the presence of electronic media under light, and the photo current could be improved further by the adding of some additives.
