A heterojunction film solar cell of glass/ITO/CdS/PbS/Al

A film solar cell was made with a structure of Glass/ITO/CdS/PbS/Al. CdS film was obtained by thermal evaporation. PbS film was prepared by a simple solid-solid reaction. The solar cells are photosensitive in a large spectral range (extending from near infrared to high energy side regions). The cell with the area of 0.15 cm(2) without any special treatment has shown the values of open-circuit voltage (Voc) of 138 mV and short circuit current (Jsc) of 0.01 mA/cm(2) with the efficiency of 0.33 % and the fill factor (FF) is 0.26 under illumination intensity of 100 mW/cm(2).
