Recently there has been a notable interest of the scientific community to develop organic photovoltaic (OPV) technology as a mean of renewable energy source since it combines low-cost and easy fabrication. We have fabricated and tested plastic solar devices (OPVs) by using the bulk heterojunction approach. OPVs were prepared by blending 6-Nitro-3-(E)-3-(4-dimethylaminophenyl)allylidene)-2,3 dihydrobenzo[d][1,3,2]-oxazaborole (M1) and (E)-3-(4-Dimethylaminophenyl)allylidene)-2,3-dihydrobenzo[d]-[1,3,2]oxazaborole (M2), which are conjugated and non-linear low molecular weight molecules prepared in our laboratories, and the well known photoconductor polymer MEH-PPV; fullerene PC61BM was the sensitizer. The morphology of thin polymer films prepared by using the spin coating technique was analyzed by Atomic Force Microscopy (AFM). For the electric contact, commercial and transparent indium tin oxide (ITO) deposited on glass slides was used, and a metal alloy of Pb/Bi/Cd/Sn as cathode, was easily deposited on the polymer film by melting the alloy at 75 °C. Open circuit voltages (Voc) of ~ 700 mV and short circuit currents (Jsc) of ~ 0.75 mA/cm2 under solar (AM1.5) illumination were measured for MEH-PPV and M1 based samples. For OPVs cells based on mixtures of either M1 and MEH-PPV or M2 and MEH-PPV there was a large electrical enhancement showing Voc ~ 700 mV and Jsc ~ 2.0 mA/cm2. OPVs cells were also tested under Xe-lamp illumination. Measurements from the I-V curves gave electrical efficiencies close to 1%.","PeriodicalId":359625,"journal":{"name":"Symposium on Optics in Industry","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126154806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A polarized laser beam passed through a photo-elastic modulator was used to measure system changes in optical rotation. Results using both the air-convective and the ohmic heating systems showed that when the protein system was heated, an increase in absolute value of optical rotation occurred close to the temperature of denaturation of the protein. Both heating systems were compared, evaluating data points spread and variation in calculated temperature of denaturation for the replicates. Although no improvement in these parameters was obtained with ohmic heating when compared to those obtained with the air-convective system, the optical change related to protein denaturation was more clearly observed. Because ohmic heating strongly interacts with the sample under study, samples with low polarity and not susceptible to electrolysis should be used to avoid electrical effects; regardless, ohmic heating coupled to optical systems could also be a useful tool for the evaluation of interaction of electric field with biological systems optically active.","PeriodicalId":359625,"journal":{"name":"Symposium on Optics in Industry","volume":"715 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122992580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The new devices of sensing through optical systems, have given a new vision of measurement and instrumentation, guiding to new studies on designs and prototypes of themselves. An example of these developments is the advance in devices of sensing in fiber optic, such is the fiber optic gyroscope (FOG) which is based on the Sagnac effect. This device has a great sensitivity because the area enclosed by the interferometric ring, is through a fiber optic coil, which increases the sensitivity and diminishes the size of the device. It is possible to indicate that in previous years, with the technology then existing, the utility to use the Sagnac effect like a gyroscope was very limited, because it was just employed to measure angular movements of great magnitudes and with very big areas, since there was not the optical detection systems of the great sensitivity that now exist or coherent sources with high power, indispensable elements in the implementation of the system. For that reasons, the application of this effect began to grow with the development of the fiber optic, and was possible diminish the size and increase the area of the device. Thus the Sagnac effect in volume optics was relegated by the fiber optic interferometer. Nevertheless using the new electronic systems of amplification and optoelectronic devices that now exist, we have rescued the Sagnac effect in volume optics to make measurements of angular velocities in an interferometric system of 0.25m2. For this work, was necessary to create a detection system of great quality, this was made using a detection method of the interference lines and amplification of the interferometric pattern.","PeriodicalId":359625,"journal":{"name":"Symposium on Optics in Industry","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121403318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
