Application of CuSCN and PEDOT:PSS as hole transport material in perovskite solar cell

Perovskite is a promising material to produce low-cost high-performance solar cell. Hole transport material is a material that usually use in perovskite solar cell to transport hole from perovskite layer. CuSCN and PEDOT:PSS is an inorganic and organic material that can be utilized as hole transport material. CuSCN and PEDOT:PSS is widely use in perovskite solar cell because of its suitable energy level and low-cost material. However, acidic and hygroscopic nature of PEDOT:PSS and solvent of PEDOT:PSS precursor limit the fabrication of perovskite solar cell into inverted p-i-n structure. In this paper, we reported a fabrication of regular n-i-p perovskite solar cell structure using CuSCN and PEDOT:PSS as hole transport material with simple method and low-cost manner. The result is a device with VOC of 1.00 V, ISC of 8.33 mA, fill factor of 0.49, and efficiency of 1.81%.
