Abstract

Fabrication of Dye-Sensitized Solar Cells (DSSC) using working electrodes composed of a mixture of TiO2 and 14% of graphite, which then denoted as TiO2:C14%, has been done. The TiO2:C14% colloid was deposited on a conductive Fluorine Doped Tin Oxide (FTO) glass substrate by using sol-gel-spin coating at the speed of 1500 rpm for 50 seconds. This thin layer was then immersed for 24 hours in different dye solutions extracted from Rosella petals (hibiscus sabdariffa), black glutinous rice (oryza sativa) and purple sweet potato (ipomoea batatas). Composition materials used to fabricate the solar cells were characterized by using x-ray diffraction (XRD) and scanning electron microscope (SEM). The power conversion efficiency (PCE) of the solar cells was measured by using a set of I-V characteristic circuit. The result showed that the highest PCE of 3 x 10-3 % was obtained from the cells based on dye extracted from rosella petals compared to those from black glutinous rice and purple sweet potato.   Keywords: DSSC, dye, rosella, TiO2, spin coating, XRD, efficiency.

Abstract

The research  on the influence of exposure factor on radiographic image quality has been conducted. This research uses phantom, water in plastic container as human substitute with focus film distance (FFD) 100 cm and broad field of irradiation 15 cm × 15 cm. The exposure conditions are given by exposure factors including variations in tube voltages of 60 kV, 65 kV, 70 kV, 75 kV, 80 kV called standard techniques or routine voltage techniques and the time flow is as big as 20 mAs, 25 mAs and 30 mAs. The results showed that the image quality will decrease with the use of current and time high. Image quality can be seen on gray-level histogram using java Image-J Basics version 1.38 software to get optimum value from exposure factor on image quality.
