DFT and experimental investigation was used for the material design on the core engineering in N,N-bis(4-methoxyphenyl)naphthalen-2-amine derivative-based hole transporting materials for perovskite solar cell applications.

Dual functional inorganic CuSCN for efficient hole extraction and moisture sealing of MAPbI3 perovskite solar cells

Most high-performing organic-inorganic hybrid perovskite solar cells (PSC) are fabricated using expensive organic hole-transporting materials (HTM). The poor moisture- and thermal-stability of organic HTM is a significant factor contributing to...

Novel Anthracene HTM Containing TIPs for Perovskite Solar Cells

Recently, perovskite solar cells have been in the spotlight due to several of their advantages. Among the components of PSCs, hole transporting materials (HTMs) re the most important factors for achieving high performance and a stable device. Here, we introduce a new D–π–D type hole transporting material incorporating Tips-anthracene as a π–conjugation part and dimethoxy-triphenylamine as a donor part (which can be easily synthesized using commercially available materials). Through the measurement of various optical properties, the new HTM not only has an appropriate energy level but also has excellent hole transport capability. The device with PEH-16 has a photovoltaic conversion efficiency of 17.1% under standard one sun illumination with negligible hysteresis, which can be compared to a device using Spiro_OMeTAD under the same conditions. Ambient stability for 1200 h shown that 98% of PEH-16 device from the initial PCE was retained, indicating that the devices had good long-term stability.
