Inorganic Hole Transport Material to Improve Performance and Stability of Perovskite Solar Cells
Organic-inorganic hybrid lead trihalide perovskite solar cells (PSCs) have shown great potential for practical application in photovoltaic field with the rapid advancement of power conversion efficiency (PCE) from the initial 3.8% to a certificated 23.3% during the past few years. However, the instability of PSCs is regarded as the vital problem that restricts its progress of commercialization and industrialization in reality. Carbon electrode with low cost and high stability has exhibited powerful magnetism and competitiveness for the practical application of PSCs in the future compared to noble metal counterpart. Nonetheless, several issues such as poor interface contact with perovskite, obvious hysteresis behaviour, and inferior power conversion efficiency obstruct its further development. A simple yet effective method was applied by introducing CuSCN as hole transport layer to modify the interface of perovskite and carbon layer and impede the hysteretic feature in carbon-based planar heterojunction perovskite solar cells.
