abstract = {Wide-band-gap perovskite solar cells are a good spectral
match to indoor lighting and have the potential for
high-efficiency indoor energy harvesting. A
perovskite-charged battery is shown to operate at both
one-sun and indoor lighting conditions with high efficiency.
We demonstrate energy harvesting and storage from 300 lux to
AM1.5G illumination realized using wide-band-gap lead halide
perovskite (CH3NH3Pb(I0.8Br0.2)3) modules directly coupled
to a high-rate-capable sodium-ion battery
(NaTi2(PO4)2@CNF/1M NaPF6 in diglyme/Na) without power
electronics. We show a high power conversion efficiency
(PCE) of $43.9\%$ for perovskite solar modules under
high-intensity LED illumination (24.5 mWcm−2), $31\%$ PCE
under 500 lux light-emitting diode (LED) illumination, and
an overall efficiency of $26.4\%.$ The present setup could
form the foundation of future indoor light-harvesting
solutions for internet-of-things devices and sensors.},
