The simulation results showed that the solar cell performance such as V-oc and FF were strongly affected by the work function of TCO films due to band bending. The experimental analysis was carried out by preparing Zn-In-Sn-O films with varying work function by varying the composition. The compositional dependence of the work function, optical and electronic properties of Zn-In-Sn-O films was examined, and the performance of the silicon heterojunction solar cells with corresponding TCO films was analyzed. The electrical properties and work function in Zn-In-Sn-O films were significantly influenced by Zn content, and Zn-In-Sn-O film with 12.7 at.% Zn content, which had the highest work function and lowest resistivity among the studied films, resulted in the highest conversion efficiency of solar cell due to increased V-oc and FF. It was shown that the behavior of performance parameters in silicone heterojunction solar cells closely correlated with the work function and electrical properties of TCO films.
