“…Recently, several research groups showed that the orientation of BR on the surface of nanoparticles also influence its performance [8][9]. The dye sensitizing effect of BR was enhanced by orientating BR molecules in a highly ordered manner towards TiO 2 nanoparticles film.…”

Bacteriorhodopsin (BR) is a light driven proton pump firstly found in the membrane of halophilic archaea. BR absorbs wide range of visible light with high quantum efficiency. To elucidate the sensitizing effect of BR, we tested the photocatalytic degradation of phenol with BR-sensitized TiO2 nanoparticles and compared with that of Alizarin red (AR). When the concentration of BR was 13.1 mg/L (4.9×10-7 mol/L), 23.8% of phenol was degradated after 2 hours of light irradiation. The degradation percentage was 3.5 times higher than that with TiO2 nanoparticles alone and similar to that sensitized by AR (20.1%). The possibilities and approaches to increase the sensitizing performance of BR were discussed.

All these studies suggest that the preferential molecular orientation of bR towards TiO 2 film could be an important factor in obtaining larger photo current out of bR in solar cells and most likely could surpass the performance of other bio-sensitizer such as cholorophyll, if highly oriented bR is achieved.…”

Bacteriorhodopsin (bR) is a membrane protein found in the archae Halobacterium salinarum. Here, we studied wild type bR and especially the triple mutant bR, 3Glu [E9Q/E194Q/E204Q], in combination with wide gap semiconductor TiO2 for their suitability as efficient light harvester in solar cell. Our differential scanning calorimetry data show thermal robustness of bR wild type and 3Glu mutant, which make them good candidates as photosensitizer in solar cells. Molecular modeling indicates that binding of bR to the exposed oxygen atoms of anatase TiO2 is favorable for electron transfer and directed by local, small distance interactions. A solar cell, based on bR wild type and bR triple mutant immobilized on nanocrystalline TiO2 film was successfully constructed. The photocurrent density-photo voltage (J-V) characteristics of bio-sensitized solar cell (BSSC), based on the wild type bR and 3Glu mutant adsorbed on nanocrystalline TiO2 film electrode were measured. The results show that the 3Glu mutant displays better photoelectric performance compared to the wild type bR, giving a short-circuit photocurrent density (J(sc)) of 0.09 mA/cm2 and the open-circuit photovoltage (V(oc)) 0.35 V, under an illumination intensity of 40 mW/cm2.

“…Integrated transmitters [1,2], photoreceivers [3][4][5], and phototransceivers [6][7][8][9] are commonly used optoelectronic components in these applications. More recently, OEICs are being employed for on-chip transmission of information and in the emerging field of silicon photonics [10,11].…”

A rolled-up microtube optoelectronic integrated circuit operating as a phototransceiver is demonstrated. The microtube is made of a InGaAs/GaAs strained bilayer with InAs self-organized quantum dots inserted in the GaAs layer. The phototransceiver consists of an optically pumped microtube laser and a microtube photoconductive detector connected by an a-Si/SiO2 waveguide. The loss in the waveguide and responsivity of the entire phototransceiver circuit are 7.96 dB/cm and 34 mA/W, respectively.
