Perovskite solar cells (PSCs) have received a remarkable attention compared to the other types of solar cells due to their high carrier mobility, low recombination rate, and rapid increase in terms of efficiency in short time. However, two essential parameters being stability and cost are still challenging with these kinds of solar cells. Hole transport materials (HTMs) play an important role in PSCs as they can be effective in the charge transportation, determining the device stability and having a large share of cell costs, and overall resulting in the enhancement of open-circuit voltage (V-oc), short-circuit current (J(sc)), and fill factor (FF). In addition to the organic HTMs which are widely used in PSCs, various inorganic HTMs mainly divided into the oxide and sulfide subgroups, have been developed in order to improve both stability and cost of PSCs. Herein, we provide an overview of the diverse types of HTMs, from organic to inorganic, especially oxide and sulfide inorganic HTMs and investigate the physical properties, synthesis, and their applications in various PSCs for both mesoporous and planar structure in the hope of encouraging further research and the optimization of these materials.
