| Summary: | 碩士 === 國立中興大學 === 機械工程學系所 === 94 === Chloroplast is the most efficient solar energy conversion cell. Successful implementation of the conversion mechanism of the chloroplast can be a promising direction for new energy recourses. This research focuses on the developement of a chloroplastmimic photovoltaics based on the nanotechnology. The concepts of the proposed chloroplastmimic photovoltaics are using photocatalysis to resolve water into H+ and •OH, applying artificial thylakoid membrane to separate cells of H+ with different concentrateions such that concentration gradient of H+ can be generated, generating current by the diffusion of H+ due to concentration gradient.
The ion diffusion property of a real cell membrane is imitated by an anodic aluminum oxide (AAO) membrane. The hydrolysis function of the enzyme in chloroplast is performed by a titania (TiO2) and carbon nanotube (CNT) combined photocatalysis to shift the absorbing spectrum of the pure titania form UV to visible light. An electrochemistry bath that used the AAO membrane as the filter to separate two vessels with concentration gradient is built to measure the photocurrent of the proposed chloroplastmimic photovoltaics.
Experimental results demonstrate that the proposed simple chloroplastmimic photovoltaics can generate photocurrent directly from the sun light. Further applications can then be expected.
