室内光伏是低功耗电子产品（如快速增长的物联网）的最佳可持续和可靠的能源之一。在模拟的室内环境下，研究了具有三种基准器件结构-具有交替空穴传输层（HTLs）的中孔PPV（mPPV）和倒置PPV（iPPV）以及碳基PPV（cPPV）的Percent光伏（PPV）电池。使用典型的Spiro-OMeCl 2作为HTL的mPPV电池在200 lux下显示出最高的最大功率密度（P-max）19.9 μ W cm（-2），在1000 lux下显示出最高的最大功率密度（P-max）115.6 μ W cm（-2）（无遮蔽），这是室内PV中最好的。有趣的是，当PTAA用作mPPV电池中的HTL时，在室内光环境下P-max下降到几乎为零，而其在一个太阳下的性能保持相似。另一方面，当PEDOT：PSS被Poly-TPD代替作为iPPV电池中的HTL时，在室内光下的P-max显著改善，并且与最佳mPPV电池的P-max相当。室内性能的这种显著差异与它们的漏电流密切相关。HTL-自由的cPPV细胞，通过完全可升级的技术制备，显示出一个有前途的P-max为16.3和89.4 μ W cm（-2）下200和1000勒克斯，分别。制作了实际规模的5 × 5cm（2）cPPV模块，作为真实的应用的演示。
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 (P-max) of 19.9 mu W cm(-2) under 200 lux and 115.6 mu W 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 P-max 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 P-max 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 P-max of 16.3 and 89.4 mu W cm(-2) under 200 and 1000 lux, respectively. A practical scale 5 x 5cm(2) cPPV module is fabricated as a demonstration for real applications.
