Study of photoelectrochemical effect of PbS with CuS

Solar energy has been considered as a renewable energy source in recent years. To avoid global warming and provide energy that people needs, the energy production of the sun plays an essential role. installing solar cells can provide the electricity, also with this way the cost of the electricity is getting reduced by half, that the companies demand from subscribers. Nowadays in industry uses silicon cells that have high costs and efficenciy of 10%. For this reasons, researchers are looking for a replacement for silicon. In this research (𝑝𝑏𝑠)𝑥(𝑐𝑢𝑠)𝑥 were grown on ITO glass substrates by successive ionic layer adsorption and reaction (SILAR) technique (1). Diffrent thin film cells were made of various cus and pbs ratio. Film’s behavior was studied in light and dark with electrochemical techniques (cyclic voltammetry and chronoamperometry) in temperature room(2,3). (𝑝𝑏𝑠)𝑥(𝑐𝑢𝑠)𝑥 film was much more sensitive to light and dark than ITO glass. As the ratio of cus to pbs increased, this sensitivity became more.
