A Solar Cell Made by a Hybrid Film of P3HT and Cubic-Like PbS
Cubic-like lead sulfide (PbS) films were in situ fabricated on lead (Pb) foil on a large scale by solvothermal method. Ethanol and ethylenediamine were used as the solvent. The films were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), absorption and the Fourier transformation-infrared (FT-IR) spectra. A solar cell was made by the hybrid film of P3HT and cubic-like PbS. The solar cells are photosensitive in a large spectral range (visible and near infrared regions). The cell with the area of 0.20 cm2 without any special treatment has shown the values of open-circuit voltage (Voc) of 250 mV and short circuit current (Jsc) of 0.01 mA/cm2 with the efficiency of 0.01 % and the fill factor (FF) is 0.36 under illumination intensity of 100 mW/cm2.
