Photocurrent generation by recombinant allophycocyanin trimer multilayer on TiO2 electrode

Dye-sensitized solar cells based on natural and artificial phycobiliproteins to capture low light underwater

“…All SEM images confirmed that the B-PE was successfully immobilized on a mesoporous TiO 2 electrode with a multilayer of non-specific orientation. It is possible that electrostatic interactions, especially hydrogen bonds, which are the strongest noncovalent forces in biological systems through functional groups such as carbonyl, amide, or imidazole, especially in macromolecules, are responsible for the multilayer adsorption, as noted previously [29,34].…”

“…Therefore, the artificial synthesis of PBPs has received extensive attention. In our previous research, we used a recombinant APC trimer to sensitize a TiO 2 nanophotoanode and constructed a DSSC based on the recombinant PBP [34]. The short-circuit current density and photoelectric conversion efficiency of the DSSC were 0.73 mA/cm 2 and 0.26%, respectively under a light intensity of 100 mW/cm 2 .…”

Progress in biosynthesis of phycobiliprotein

“…荧光蛋白(FPs)是生物医学研究的重要工具之一. 20多年前, Chalfie等人 [74] 将Aequorea victoria的绿色 [76] 将重组APC三聚体作为敏化材料, 构建了 基 于 重 组 PBPs 的 DSSC, 该 DSSC 的 测 试 结 果 显 示 : Photosynthesis has existed on the earth for about 4 billion years, and the photosynthetic organisms have emerged with the production of photosynthesis. In order to effectively capture light energy and adapt their living environment, algae and higher plants have evolved different light-harvesting antenna systems during the long evolution, one is the chlorophyll based light harvesting systems present mainly in terrestrial organisms, such as higher plants; and the other is the phycobiliprotein (PBP) based phycobilisome system mainly in aquatic organisms, such as cyanobacteria, red algae and cryptophytes.…”
