Efficient indoor light harvesting with CH3NH3Pb(I0.8Br0.2)3 solar modules and sodium-ion battery
Source abstract
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.
