In the context of energy harvesting for autonomous sensors placed indoors, an evaluation fractional open-circuit voltage (FOCV) as a tracking technique low-area photovoltaic (PV) cells is carried out in this article. The applicability and limitations FOCV are experimentally demonstrated by means four commercial FOCV-based chips (BQ25570, ADP5092, SPV1050, MAX20361) two PV different technology (amorphous monocrystalline). experimental results show that efficiency quite high (i.e., more than 98 %) range between 250 1500 lux and, therefore, overall practically equal to ensuing power management unit (PMU). However, at low levels illuminance (e.g., 100 lux), depends on both itself fraction be applied does not remain constant) implementation charging process capacitors involved input stage). These can partially compensate each other some scenarios so also obtained lux. With knowledge previous limitations, methods increasing suggested proven.

Abstract The building sector accounts for 36% of energy consumption and 39% energy-related greenhouse-gas emissions. Integrating bifacial photovoltaic solar cells in buildings could significantly reduce related greenhouse gas Bifacial should be flexible, bifacially balanced electricity production, perform reasonably well under weak-light conditions. Using rigorous optoelectronic simulation software the differential evolution algorithm, we optimized symmetric/asymmetric CIGS with either (i) homogeneous or (ii) graded-bandgap photon-absorbing layers a flexible central contact layer aluminum-doped zinc oxide to harvest light outdoors as indoors. Indoor was modeled fraction standard sunlight. Also, computed responses using LED illumination different intensities. optimal cell is predicted 18%–29% efficiency 0.01–1.0-Sun illumination; furthermore, efficiencies 26.08% 28.30% weak 0.0964 mW cm −2 0.22 intensities, respectively, are predicted.
