Abstract
In the field of energy harvesting for autonomous sensors located indoors, this work analyses the line-arity of low-area photovoltaic (PV) cells of different technology while subjected to different levels of illuminance coming from either artificial or natural sources. For indoor artificial lighting (to be precise, cold LED), the PV technologies under test show a linear response, except for the monocrystalline technology. However, for indoor natural light, only PV cells belonging to the III-V technology show a linear response. Monocrystalline PV cells show an increasing quadratic response, whereas amor-phous and organic PV cells have a decreasing quadratic response. Accordingly, the most appropriate technology to leverage the indoor energy coming from the natural light is the monocrystalline.
