A scalable, hysteresis-free and planar architecture perovskite solar cell is presented, employing a flame spray synthesized low-temperature processed NiO (LT-NiO) as hole-transporting layer yielding efficiencies close to 18%. Importantly, it is found that LT-NiO boosts the limits of open-circuit voltages toward an impressive non-radiative voltage loss of 0.226 V only, whereas
PSS suffers from significant large non-radiative recombination losses.
本文提出了一种可扩展、无迟滞且平面的钙钛矿太阳能电池架构，采用火焰喷涂合成的低温处理 NiO（LT-NiO）作为空穴传输层，效率接近 18%。重要的是，研究发现 LT-NiO 将开路电压的极限提高到了令人印象深刻的非辐射电压损耗仅 0.226V，而 PEDOT: PSS 则存在严重的大非辐射复合损耗。
