Abstract

Has been fabricated and characterized an organic solar cell based onCopper phthalocyanine (CuPc) and 3, 4, 9, 10 perylenetetracarboxylic diimide(PTCDI). CuPc and PTCDI layer sandwiched between two different electrode ofITO and Ag by vacuum evaporation so solar cell structure isITO/CuPc/PTCDI/Ag. UV-Vis spectra of ITO/CuPc/PTCDI/Ag is 400 nm to 760nm which is superposition of CuPc layer and PTCDI layer. From characterizationof current density – voltage (J-V) show that current under illumination higher thandark current. The power conversion efficiency of 0.40 % under illumination 100mW/cm2 are obtained with fill factor 0.33.

Abstract

Telah dilakukan pengujian karakteristik absorpsi larutan porphyrin dan responsivitas cahaya. Larutan senyawa molekul porphyrin diisolasi dari mikroalgae spirulina. Pengujian fotokonduktivitas dalam kondisi gelap diperoleh sekitar 0,9x10-4 ohm-1.cm-1 sedangkan pada kondisi diberi intensitas radiasi 0,5 W.m-2, 10 W.m-2 dan 16 W.m-2 diperoleh fotokonduktivitas sekitar 1,5x10-4 ohm-1 cm-1. Spektrum absorbansi larutan porphyrin mempunyai soret band sekitar 410 nm dan Q-band sekitar 660 nm. Dari hasil perhitungan responsivitas cahaya pada larutan porphyrins dengan panjang gelombang 410 nm dan 660 nm mempunyai tanggapan cahaya yang baik yaitu sekitar 3,92x10-2 ampere/watt dan 5,53x10-2 ampere/watt. Sedangkan pada panjang gelombang lainnya diperoleh sekitar 1,39x10-9 ampere/watt. Hal ini cukup potensial bahwa material porphyrins alam dapat digunakan sebagai material photonics pada devais foto.

Abstract

A dye-sensitized solar cell (DSSC) is a device for converting photons from sunlight into electrical energy. In a DSSC, an important role is played by the dye sensitizer, which absorbs light and injects excitation electrons into the conduction band of a semiconductor oxide. As the sensitizer, complex ruthenium-based dyes provide high conversion efficiency but are expensive and scarce. As alternatives to Ru-based dyes, natural ones extracted from plants are environmentally friendly, inexpensive, and abundant. However, in DSSCs natural dyes are yet to offer higher conversion efficiency than that of complex Ru-based dyes, given low absorption in the visible range and low stability. High-purity textile dyes have been investigated as sensitizers in DSSCs, and dispersive azo dyes for textiles have been purified successfully by column chromatography, with a minimum purity of 97.3%. As such, textile-dye extract could be used as a dye in a DSSC by purifying the former using column chromatography. This article describes research on (i) DSSC fabrication and characterization, (ii) column chromatography for purifying dispersive azo dyes, (iii) the absorbance of several types of textile dye, (iv) the characteristics of the textile dye Remazol Red RB-133, and (v) the performance of a DSSC based on that dye.

Abstract

Physics learning aims to provide provision experience and skill process, increase the creativity and scientific attitude of students. A scientific attitude is needed in learning science, including physics, because when students have a high scientific attitude, understanding of the concept and learning outcomes will increase. The purpose of this article is to look at the profile of students' scientific attitudes on the dimensions of attitudes, critical attitudes to facts, critical thinking, respect for data / facts, open thinking and cooperation in learning physics. This study aims to describe the scientific attitude profile of the XII grade students of SMA YPPK Teruna Bakti. The method used in this research is quantitative quantitative. The data was collected through a non-test instrument in the form of a questionnaire based on four of the six dimensions of scientific attitudes according to Harlen. The test was conducted on 35 students. The test results showed that the total average level of mastery was 73%. Scientific attitude per dimension, for curiosity dimension 75%, critical thinking dimension 72%, critical thinking dimension to data / facts 67%, open thinking dimension 77% and cooperation 74%.Keywords: Scientific Attitude, Assessment, Physics

Abstract

A DSSC has a good performance seen from the ability of the photoanode to absorb sunlight. The use of photoanodes uses a semiconductor material, namely ZnO. However, in use, ZnO has the disadvantage of low optical and electrical properties, which results in low DSSC efficiency. So in this research, efforts are made to add Cu-Ag double doping to improve optical and electrical properties that will increase the efficiency of DSSC. ZnO/Cu-Ag photoanodes were prepared using the sol-gel spin coating method with doping variations of 0%, 1%, 2%, and 3%. Characterization was carried out using a UV-Vis spectrophotometer to see the absorption area and determine the band gap energy of the ZnO photoanode. I-V Keithley was used for current and voltage characterization to determine the conductivity of the ZnO photoanode and the efficiency of the DSSC. The results of the research show the effect of increasing the optical properties of ZnO photoanodes by decreasing the band gap energy along with the increase in doping concentration, namely 3.29 eV, 3.24 eV, 2.44 eV, and 2.40 eV. In addition, there is an increase in conductivity on the ZnO photoanode with the highest conductivity at doping concentration of 3% which is 0.1006 Ω-1m-1 with an increase of 6 times compared to the pure ZnO photoanode of 0.0163 Ω-1m-1. The improved optical and electrical properties of ZnO/Cu-Ag photoanodes have an impact on increasing the efficiency value of DSSC with the optimum efficiency achieved at 1% doping concentration of 0.0291% with an increase of 16 times compared to the use of pure ZnO photoanode of 0.00018%. The addition of Cu-Ag doping to ZnO improves the optical and electrical properties of the photoanode, enhancing DSSC efficiency with an optimum at 1% doping concentration.

Abstract

The purpose of this research is to measure students critical thinking skill in solving scientific literacy using a metacognitive test based on scientific literacy. This research is descriptive research. The subject of this research is 99 students of grade XI in SMA Batik 2 Surakarta. Data collection methods used are test methods which using a metacognitive test based on scientific literacy. Data analysis techniques use quantitative descriptive analysis. The results showed that the achievement of scientific literacy is still low at below 50% for all category. This is due to students critical thinking skill in solving all category of scientific literacy problem is still low. Low student critical thinking skill in solving science as a body of knowledge in the assessment stage with the percentage achievement is 21%. Low percentage achievement of critical thinking skill in solving science as a way of thinking is a clarification (34%), assessment (46%), inference (26%), and strategy (12%). Low percentage achievement of critical thinking skill in solving science as a way of investigating is assessment (39%), inference (5%), and strategy (6%). Low student critical thinking skill in solving science as an interaction between technology and society in the assessment stage with the percentage achievement is 31%

Abstract

This research aims to determine the differences in the scientific attitudes of students who are given physics learning with the PBL model using experimental methods and project methods on static fluid material. The method used in this research is quantitative with a quasi-experimental approach using two independent group designs, namely the experimental group I using the PBL model-experimental method and the practical group II using the PBL model-project method. Subjects in this study were 65 students of class XI SMA YPPK Teruna Bakti obtained using cluster random sampling technique. Data obtained through a scientific attitude questionnaire instrument consisting of 15 items that have been tested for validity and reliability using SPSS 23.0.  Then, the prerequisite test (normality and homogeneity) was carried out and continued with hypothesis testing. The t-test result of 0.026 shows a difference in the average scientific attitude between students who are given learning using the PBL model with the experimental method and students who are given learning using the PBL model with the project method even though the average score for both. Not significantly different, namely in the experimental class 74.14 and the project class 70.10.
