KESTABILAN SEL SURYA DENGAN FOTOSENSITIZER EKSTRAK ZAT WARNA KULIT JENGKOL (Pithecellobium lobatum Benth.)
Abstract: The stability of
solar cell using the extract jengkol’s dyes as photosensitizer has been
investigated. Their components consisting of working electrode TiO2, counter
electrode graphite 2B pencil, and electrolyte I-/I3-. Dye extract was
characterized by using UV-Vis Spectrophotometer. It had been shown that the dye
obtained have wider absorbtion in visible light range. A series of solar cell were measured for their
voltage value and current electricity, based on the variation of time of soaking from 10 until 60 minutes.
Result indicated that voltage and current electricity at 60 minutes of soaking
gave better performance with 420 mV and 0,0148 mA, respectively. The stability
of the solar cell was measurde based on its life duration. Addition of TiO2
gave absorbance from 1,111 – 0,632 where as without addition of the oxide then
the absorbance are shifted from 1,680 – 0,570 measured at 530 nm.
