Universal Approach

A universal vertically-rotated (VR) methodology is proposed to rotate the crystal orientation of 2D perovskites, which improves charge transport properties by several orders of magnitude and boosts the efficiency of 2D (n ≤ 4) PSCs to above 17%.

: 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.
