| Summary: | Solid state polymer electrolyte blend of polyethylene oxide, chitosan, ammonium iodide,
and iodine crystals has been prepared by solution cast technique. The highest ionic conductivity of
the polymer electrolyte was 1.18 × 10−5 S cm−1 at room temperature. Addition of chitosan to the
electrolyte has improved its mechanical properties. A photovoltaic junction with configuration
ITO/TiO2-solid state polymer blend electrolyte/ITO has been constructed. The open circuit voltage
Voc, short circuit current density Jsc, and fill factor FF% obtained from the photovoltaic system
under white light illumination of 100W Tungsten lamp are 320-350 mV, 0.59-2.5μAcm-2 and 42%-
59% respectively. |
