In this study, a solar cell with a glass/ITO/CdS/PbS/Al structure was constructed. Both window (CdS) and absorption (PbS) layers were deposited by chemical bath deposition (CBD) method. The CdS window layer was deposited on ITO-glass. The PbS nanocrystalline thin film was prepared with and without triethanolamine on CdS films at bath temperature of 25 °C. CdS and PbS nanocrystals were identified using XRD and SEM. The cells are photosensitive in a large spectral range (at visible and near infrared regions). The cell with absorbing layer obtained from the bath without TEA has higher efficiency with the following parameters: the open circuit voltage (Voc) is 275 mV, short circuit current (J sc) is 12.24 mA/cm 2, maximum voltage (V max) is 165 mV and maximum current (J max) is 7.11 mA/cm 2with the efficiency η = 1.31 %, fill factor FF is 32 % under the illumination intensity of 90 mW/cm2. The cells have an area of 0.15 cm 2.
