PublicationPotential of roselle and blue pea in the dye-sensitized solar cell( 2017-09-26)
;Dayang Suriani ;Gomesh NairThis paper discovers the use of natural dyes from Roselle flower and Blue Pea flower which act as a sensitizer in DSSC and in addition has a potential in absorbing visible light spectrum. The dyes were extracted using distilled water (DI) and ethanol (E) extract solvent in an ultrasonic cleaner for 30 minutes with a frequency of 37 Hz by using 'degas' mode at the temperature of 30°C. Absorption spectra of roselle dye and blue pea dye with different extract solvent were tested using Evolution 201 UV-Vis Spectrophotometer. It was found that Roselle dye absorbs at a range of 400 nm - 620 nm and Blue Pea absorbs at the range of wavelength 500 nm - 680 nm. Fourier-Transform Infrared (FTIR) was used to identify the functional active group in extract dye. The concept of Dye-Sensitized Solar Cell (DSSC) similar to photosynthesis process has attracted much attention since it demonstrates a great potential due to the use of low-cost materials and environmentally friendly sources of technology. -
PublicationEffects of Appliances to Voltage, Current, Power Factor and Harmonic Distortion( 2004)
;Ismail Daut ;Soib TaibKamsani Abdul MajidPower utility always get blame if there are power interruption occurred in residential areas. Many of the residential customers are unaware, that is electrical appliance itself one of the reason that contribute to power quality problem. Effects of appliances a/so can harm other sensitive equipment as we/las electrical distribution system. This paper studies the effects of the appliances to power quality. Appliances that are used in the study are personal computer, fluorescent light, iron, LCD monitor, motor & driver, television, hand drill, laptop and jig saw. Waveform of the phase voltage and current, power components, and distortion of voltage and current for all appliances have been recorded and analyzed using Reliable Power Meter. In this paper concepts of power factor and effects of harmonics are reviewed. Subsequently voltage and current waveform, voltage total harmonic distortion, current total harmonic distortion and power factor are analyzed and discussed.4 13
