Silver sulfide thin film solar cells: materials, fabrication methods, devices, and challenges

“…The sulfuration method is characterized by its simplicity in processing, higher cost, and specific conditions required to obtain the desired product, such as low Gibbs free energy of reaction, temperature, inert gas atmosphere, and sulfuration agent concentration. [71][72][73] E. Barrera-Calva et al successfully prepared well-crystallized Ag 2 S thin films using a simple sulfuration method. The specific steps are as follows: firstly, a certain thickness of metallic Ag film is deposited on a glass substrate using a high-vacuum thermal evaporation apparatus.…”
