Formatted abstract
Mesoscopic perovskite solar cells using stable CH3NH3PbI2Br as a light absorber and low-cost poly(3-hexylthiophene) (P3HT) as hole-transporting layer were fabricated, and a power conversion efficiency of 6.64 % was achieved. The partial substitution of iodine with bromine in the perovskite led to remarkably prolonged charge carrier lifetime. Meanwhile, the replacement of conventional thick spiro-MeOTAD layer with a thin P3HT layer has significantly reduced the fabrication cost. The solar cells retained their photovoltaic performance well when they were exposed to air without any encapsulation, presenting a favorable stability. The combination of CH3NH3PbI2Br and P3HT may render a practical and cost-effective solid-state photovoltaic system. The superior stability of CH3NH3PbI2Br is also promising for other photoconversion applications.
