Experimental Investigations towards the Design of Power Management System Using Indoor Photovoltaic

With the increasing popularity of Internet-of-Things (IoT) based building automation and lighting controls in the interior, the power management of IoT devices is a concern. Researchers globally are working on Indoor high-performance photovoltaics, which can power IoT devices. Here arises the need for experimentation with Indoor Photovoltaics (IPV) under varying interior lighting conditions that includes both artificial light and daylight. This paper focuses on experimental verification of the IPV characterization under indoor lighting conditions, adopting the recent human-centric lighting challenges. The paper presents empirical modeling of indoor irradiance and Photovoltaic cells to estimate its I-V characteristics and focuses on their operation at indoor illumination levels. A crucial requirement for accomplishing self-sustainability is the ability of IoT devices to be self-powered.
