What is Cadmium ion soaking treatment for solution processed CuInSxSe2−x solar cells and its effect on defect properties about?
Recombination of charge carriers due to electronically active material defects is one of the major factors limiting power conversion efficiency in solar cells. We have studied the defect behavior in CuInS x Se 2 À x solar cells fabricated through a solution process with a maximum heating temperature of 390 1C. By introducing a cadmium ion soaking step into the fabrication process, we find that the recombination rate can be reduced. Through the use of capacitance-voltage (C-V) profiling, drive level capacitance profiling (DLCP) and admittance spectroscopy analysis, the cadmium ion soaking process was found to increase the charge carrier concentration in the bulk of the absorber, and shift the energy level of the N1 defect toward the valence band edge. The soaking process was found to most obviously affect the open circuit voltage with an average improvement of 33 mV.
