Compact Layer Free Perovskite Solar Cells with a High-Mobility Hole-Transporting Layer

关键字:perovskite solar cells; compact layer free; solution processing; low-temperature processing; diketopyrrolopyrrole-based copolymer; hole-transporting layer

摘要:A high-mobility diketopyrrolopyrrole-based copolymer (P) was employed in compact layer free CH3NH3PbI3 perovskite solar cells as a hole-transporting layer (HTL). By using the P-HTL, the 6.62% device efficiency with conventional poly-3-hexylthiophene was increased to 10.80% in the simple device configuration (ITO/CH3NH3PbI3/HTL/MoO3/Ag). With improved short circuit current density, open circuit voltage, and fill factor, the higher power conversion efficiency of P-HTL device is ascribed to the higher carrier mobility, more suitable energy level, and lower interfacial charge recombination. Advantages of applying P-HTL to perovskite solar cells, such as low cost, low -temperature processing, and excellent performance with simple cell structure, exhibit a possibility for commercial applications.
