Emerging hybrid organic–inorganic perovskites with superior optoelectronic property demonstrate promising
prospect for photovoltaic (PV) applications, in particular for low-lighting indoor applications e.g. within internet
of things (IoT) networks or low-energy wireless communication devices. In order to prepare devices with high
power output under low-illumination conditions, scalable fabrication techniques are preferred for large-area
perovskite solar cells. In additions, one of the key parameters to achieve high-efficiency large-area perovskite
solar cells is to minimize the ohmic loss to further boost the solar cell efficiency. Herein, a one-step blade-coating
method assisted by hexafluorobenzene (HFB) was developed to deposit dense, large-area smooth and high-
quality perovskite films with low ohmic loss. The as-fabricated devices demonstrated power conversion effi-
ciency (PCE) of 20.7% (area of 0.2 cm2) and 16.5% (1 cm2), respectively, under standard (AM 1.5G) illumination
conditions. Besides, the large-area (1 cm2) devices demonstrated a remarkable PCE of ~ 33.8% and ~ 30.0%
under 1000 lx and 100 lx illumination provided by white light-emitting diode (LED) lamp, respectively. We
exhibited a series-connected stack of large-area (totally active area ~ 4 cm2) perovskite photovoltaic device
powering up a LED under common indoor environment as an indoor self-power indicator lamp. The analysis
using a single diode model suggests that the high performance of the large-area devices under low-lighting in-
door conditions is highly associated with the largely reduced ohmic losses, which particularly indicate that the
perovskite films by a facile and scalable blade-coating method. The presented scalable approach paves the way to
designing high-performance perovskite solar cells for a variety of emerging indoor PV applications [-]
