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

Penelitian ini mengkaji pengaruh waktu terhadap effisiensi Dye Sensitized Solar Cell (DSSC). Jarak elektroda divariasi sebesar 76 µm dan 114 µm. Karakterisasi sifat listrik menggunakan Keithley I-V meter yang dilakukan selama 21 hari dengan selang 7 hari untuk mengetahui kestabilannya. Karakterisasi I-V dengan selang waktu pengukuran menunjukkan bahwa DSSC dengan jarak elektroda 76 µm stabil hingga hari ke-7 dengan efisiensi 0,0347%. Pada jarak 114 µm stabil hingga hari ke-14 dengan efisiensi 0,0117%.

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

Have been conducted a thin film plant of CuPc (Copper Phthalocyanine) and CuPc/Ag (Copper Phthalocyanine/Argentum) at substrat ITO (Indium Tin Oxide) with evaporation method. Coat plant attenuate this use variation ofmass that equal to 50 mg, 100 mg, and 150 mg, with current deposition equal to 40 Ampere. Characterization ofCuPc thin film use Scanning Electron Microscopy (SEM) to know the thickness of the thin film, UV - VisibleSpectrophotometer to know absorbance value of CuPc thin film at wavelength of visible light, and measurement ofvoltage current by two point probe method to know the voltage current characteristics from the thin film in the darksituation and under illumination situation. From result of SEM characterization show the thickness valueprogressively along increase of CuPc materials mass. For the each deposition mass obtained thickness value(0,46 ± 0,01) until (0,92 ± 0,02) μm. UV - Visible Spectrophotometer characterization show light absorption by CuPcthin film layer in visible light, absorption happened at wavelength range 520 nm until 780 nm. From the current -voltage measurement at dark and under illumination situation obtained a current value progressively increasealong its mass increase, but decrease from illuminated to darkness.
