N719-dye based electrochemical light and temperature sensor
الملخص
In this article, electrochemical N719-Dye based integrated light and temperature sensors have been
reported. The fabricated sensor exhibits interesting features such as low cost, simple fabrication
process, high sensitivity and self-powering capability. Current-Voltage (I-V) and Electrochemical
Impedance Spectroscopy (EIS) characterizations have been performed to study the electrical and
photo-electrochemical response of the sensors. The electrochemical response has been investigated as
a function of incident light intensity and temperature. The sensors show a linear current-irradiance and
current-temperature relationships. The transient response and recovery times of the photo sensors are
220 msec and 630 msec, respectively. The measured sensor’s responsivity is 3x10-4 A/W while its
sensitivity is 7 S.m.W-1
. The above results make the newly proposed integrated light and temperature
sensor very promising and pave the way for the development of simple and cost effective light and
temperature sensors.
