Indoor photovoltaics is one of the best sustainable and reliable energy source for low power consumption electronics such as the rapidly growing Internet of Things. Perovskite photovoltaic (PPV) cells with three benchmark device architectures – mesoporous PPV (mPPV) and inverted PPV (iPPV) with alternative hole transporting layers (HTLs), and carbon‐based PPV (cPPV) are studied under a simulated indoor environment. The mPPV cell using typical Spiro‐OMeTAD as the HTL shows the highest maximum power density (Pmax) of 19.9 μW cm−2 under 200 lux and 115.6 μW cm−2 under 1000 lux (without masking), which is among the best of the indoor PV. Interestingly, when PTAA is used as the HTL in the mPPV cell, the Pmax drops to almost zero under indoor light environment while its performance under one sun remains similar. On the other hand, when PEDOT:PSS is replaced by Poly‐TPD as HTL in the iPPV cell, the Pmax under indoor light improves significantly and is comparable to that of the best mPPV cell. This significant difference in indoor performance correlates well with their leakage current. The HTL‐free cPPV cell, prepared by fully up‐scalable techniques, shows a promising Pmax of 16.3 and 89.4 μW cm−2 under 200 and 1000 lux, respectively. A practical scale 5 × 5cm2 cPPV module is fabricated as a demonstration for real applications.

钙钛矿光伏电池出色的室内性能–器件架构和中间层的影响
对于低功耗电子产品（例如快速发展的物联网），室内光伏是最佳的可持续性和可靠能源。在模拟室内环境下，研究了具有三种基准设备架构的钙钛矿光伏（PPV）电池–具有替代空穴传输层（HTL）的中孔PPV（mPPV）和倒置PPV（iPPV），以及碳基PPV（cPPV）。使用典型Spiro-OMeTAD作为HTL的mPPV电池在200 lux下显示最高最大功率密度（P max）为19.9μWcm -2和在1000 lux下显示115.6μWcm -2（无掩膜），这是最好的室内光伏。有趣的是，当PTAA用作mPPV单元中的HTL时，P max在室内光线环境下几乎降至零，而在阳光下的性能仍然相似。另一方面，当iPPV单元中的PTL被Poly-TPD代替Poly-TPD作为HTL时，室内光下的P max显着提高，可与最佳mPPV单元相提并论。室内性能的显着差异与其泄漏电流密切相关。通过完全可升级的技术制备的无HTL cPPV电池在200 lux和1000 lux下显示出有希望的P max分别为16.3和89.4μWcm -2。制造了一个实际规模的5×5cm 2 cPPV模块，作为实际应用的演示。
