Organic dyes employ in traditional Dye-sensitized solar cells (DSSC) results in both high cost and
low stability under light exposure. In this study, we present an inorganic semiconductor
heterostructure solar cell based in ordered thin film of MoS2 deposited on one-dimensional nanorods
array of TiO2 which were produced via simple two-steps by hydrothermal method. The solar cell
MoS2/TiO2 heterostructure exhibit a good fill factor, and a greatly enhanced power conversion
efficiency. The research presented here will provide a path for creating heterostructure inorganic
materials for highly efficient solar cells
