Multi-Junction Solar Module and Supercapacitor Self-Powering Miniaturized Environmental Wireless Sensor Nodes
A novel prototype based on the combination of a multi-junction, high-efficiency photovoltaic (PV) module and a supercapacitor (SC) able to self-power a wireless sensor node (WSN) for outdoor air quality acure face lotion monitoring has been developed and tested.A PV module with about an 8 cm2 active area made of eight GaAs-based triple-junction sol
