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 monitoring has been developed and tested. A PV module with about an 8 cm2 active area made of eight GaAs-based triple-junction solar cells with a nominal 29% efficiency was assembled a... https://safeersappliancers.shop/product-category/aeg-kdk911423m-sous-vide-integrated-vacuum-sealing-drawer-black-glass-stainless/
