Nanomaterials-based Sustainable Energy Harvesting Technologies: A Parametric Qualitative Comparative Study

Abstract

Everyone knows that energy demand is increasing around the globe, so we need to find sustainable and renewable sources for our needs. So energy harvesting is a good solution if you want to have an eco-friendly way of generating energy. The process where we scavenge energy from the surrounding sources and convert it into electrical power is called energy harvesting. Nanomaterials possess distinctive physical and chemical properties making them unavoidable elements in the advancement of next generation energy harvesting technology. This research article presents an overview of various energy harvesting techniques, including solar thermal electric, thermoelectric, piezoelectric, and triboelectric energy harvesting, which are enhanced by the combination of various nano materials. In this investigation comparative study is done between nanomaterials-based sustainable energy harvesting technologies. We will discuss the basics of these systems, techniques for their fabrication, performance models, challenges, and prospects in this exciting field.
