Effect of Thermal and Chemical Treatment on Electrodeposited CdTe Thin Films for Solar Cell Applications

A novel bithiophene-fulleropyrrolidine bisadducts system (bis-Th2PC 60) was synthesized and electropolymerized by chronoamperometry onto flexible ITO/PET substrates. The resulting semitransparent thin film was characterized by XPS, FT-IR, cyclic voltammetry and optical techniques, confirming the good outcome of the electropolymerization process. AFM investigations permitted to highlight an inherent disordered granular morphology, in which the grain-to-grain separation depends upon the application of bending. The electrical resistance of the thin film was characterized as a function of bending (in the range 0°-90°), showing promising responsivity to low bending angles (10°-30°). The ΔR/R 0 variations turn out to be 8 %,16 % and 20 % for bending angles equal to 10°, 20°and 30°, respectively. This study represents a first step towards the understanding of piezoresistive properties in electropolymerized fullerenes-based thin films, opening up applications as bending sensor.
