Nowadays, the hybrid organic-inorganic perovskite solar cells (PSCs) are considered as the most promising third generation photovoltaic (PV) technology with the highest increasing rate of power conversion efficiency (PCE) among other types of emerging PVs. To date, the PCE values are comparable to the most of the established photovoltaic technologies. Intensive research activities on perovskite materials and their devices have been being performed since last decade, aiming to further boost the device performance including efficiency and stability as well as to accelerate the commercialization progress of the developed technologies via different strategies. The emerging 2D black phosphorus (BP) is a novel class of semiconducting material owing to its unique characteristics, allowing them to become attractive materials for applications in a variety of optoelectronic devices. In this work, the optimized BP materials are incorporated with PSCs at the interface between the electron transport layer and perovskite absorber. Systematic characterizations have been performed on the materials and devices. The obtained results indicate that the incorporation of BP facilitates the crystallization of the perovskite and promotes the carrier transports in PSCs. The device stability with incorporation of BP is also found to be improved significantly.
