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. |
