A new type of solar cell with structure glass/ITO/CdS/PbS/conductive graphite was constructed and studied. Both window (CdS) and absorption (PbS) layers were deposited by means of the chemical bath deposition (CBD) technique. The maximum temperature employed during the solar cell processing was 70 degrees C and it did not include any post-treatment. In case of the CdS window layer, complexing agents alternative to ammonia were employed in the CBD process and their effects on the CdS films properties were studied. The solar cells are photosensitive in a large spectral range (all visible and near infrared regions); the cell with the area of 0.16 cm(2) without any special treatment has shown the values of open-circuit voltage V(oc) of 290 mV and short circuit current J(sc) of 14 mA/cm(2) with the efficiency eta = 1.63% (fill factor FF is 0.36) under illumination intensity of 900 W/m(2). It was found that the CBD-made PbS layer has a certain degree of porosity, which favorably affects its applicability in solar cell construction. The possible ways of device optimization, and in particular, the effect of the PbS grain size on its performance are discussed. (C) 2011 Elsevier B.V. All rights reserved.
