A Speculative Approach to Efficiently Harvesting Sustainable Energy

EasyChair Preprint 7315

Abstract

Energy demand will never decline in the same way as it did when the industrial revolution began and continued to flourish on energy use. The widespread use of fossil fuels leads to major environmental problems such as global warming, air and water pollution, and also has a detrimental influence on human health. Finding a safe and sustainable alternative energy source has become a sine qua non for human beings. We considered many methods for developing an energy source that could be used to generate electricity without relying on fossil fuels in both on- and off-grid circumstances. We intended to build a system that would merge two current technologies and would offer strategies for boosting their power generation efficiency. To begin, we examined tandem perovskite-silicon photovoltaic (PV) cells. Due to efficiency losses caused by heat and the module's inability to monitor the sun's direction for optimum irradiation capture, the necessity for a cooling unit and solar tracker became obvious, as did its functioning at night. An ancient technique known as Radiative Sky Cooling (RSC) was recently reintroduced to our understanding as a result of fast advances in nano-optics, nano-fabrication, and metamaterials. It can cool a system by boosting radiative heat transfer with cold space in the 8 to 13 m atmospheric window. Due to the fact that this system can now operate in direct sunlight, we investigated the subject, watched its operation, and examined if a single arrangement consisting of RSC and PV cells was conceivable. Using a thermoelectric generator as an RSC enables nighttime power generation, but at a poor efficiency, which we investigated and hypothesized several ways to enhance.

Keyphrases: Photovoltaic, Radiative Sky Cooling, Solar Tracker, renewable energy source, thermoelectric effect
