fossil fuels. One of these alternatives is that the Sun is an infinite resource of energy. Solar cells (SC), also known as photovoltaic devices, are used for the conversion of solar energy into electricity. Nowadays, silicon solar cells (firstgeneration photovoltaic technology) still dominate the photovoltaic market due to high efficiency and high device stability, despite having disadvantages such as high cost, inflexibility, and opacity, which limit their future development prospects. Fortunately, perovskite solar cells (PSCs) have undoubtedly become the super star in the photovoltaic field, and now the certified power conversion efficiency (PCE) has reached a very high level of 25.7%, which is comparable to that of crystalline silicon solar cells [1]. Holes transporting material (HTM) is one of the main factors of a perovskite solar cell, which determines the cost, energy conversion effectiveness and continuity of the device. However, most HTMs have many disadvantages, including complicated and expensive synthesis, the tendency of self-aggregation, which degrades the quality of the hole transport layer and reduces device stability and efficiency. Therefore, considerable and continuous efforts are made to develop more ideal HTMs, which should exhibit the following advantages: matching well with the valence band and conduction band of the perovskite to enable hole extraction and electron blocking, minimal absorption in the visible and NIR regions of the solar spectrum, sufficient hole mobility, excellent thermal and photochemical stability, high processability, and low cost.
