Abstract

To harvest indoor light energy via photovoltaics (PVs), this paper proposes an adaptive-fractional-open-circuit-voltage (AFOCV) maximum power point tracking (MPPT) circuit to automatically adjust the FOCV fraction under different illuminances for amorphous PV modules. Designed in 0.5-μm CMOS process, the AFOCV circuit consumes an ultra-low average current of 100 pA. Over 100-1000 lux illuminance, the measured MPPT efficiency with AFOCV is >99.6%, which outperforms that of other state-of-the-art energy harvesting (EH) ICs with conventional FOCV methods.
