A new hybrid film solar cell was made with a structure of Glass/ITO/PbS/P3HT/Al. PbS film was prepared by a simple solid-solid reaction and poly(3-hexylthiophene) (P3HT) film was obtained by a spin coating method. The solar cells are photosensitive in a large spectral range (extending from near infrared to high energy side regions). Without any special treatment, the cell with an area of 0.15 cm2 has shown values of open-circuit voltage (Voc) of 85 mV and fill factor (FF) of 0.33 under an illumination intensity of 100 mW/cm2.

Lead sulfide (PbS) magic cubes were prepared by a simple hydrothermal method without any organic solvent. The product was characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM) and absorption spectrum. A solar cell, with a structure of Al/P3HT:PbS/PEDOT:PSS/ITO/Glass, was made. By a spin coating method, a hybrid film of poly(3-hexylthiophene) (P3HT) and PbS was prepared on the PEDOT:PSS layer. The solar cells are photosensitive in a large spectral range (visible and near infrared regions). The cells, with the area of 0.15 cm2 without any special treatment, have shown the values of open-circuit voltage (Voc) of 242 mV, short circuit current (Jsc) of 0.01 mA/cm2, energy conversion efficiency (η) of 0.01 % and fill factor (FF) of 0.31 under illumination intensity of 100 mW/cm2.
