In the past decade, organic-inorganic perovskite solar cells (PSCs) have received great attentions due to their
high efficiencies and low costs. However, the commercialization of PSCs is stilled hindered by several issues such as
device performance (especially for large-area cells) and stability. Recently, two-dimensional (2D) transition metal
disulfides (TMDs) show great potentials in solving aforementioned problems due to their unique morphological structure
and electrical properties. Herein, we summarize the advancements in the recent applications of various TMDs materials as
charge transport layers in PSCs. Although some progresses have been made, there are considerable issues to be tackled in
this field. The challenges and development directions of these 2D TMDs materials for PSCs are also clarified. Lastly, the
most recent advancements about TMDs materials in some other electronic (or optoelectronic) fields are also summarized
and discussed.
