Original abstract

This paper proposes an embedded architecture, developed with nanotechnologies, for the solar harvesting and storage system adapted to high-performance electric vehicles. A known pathway to converting solar energy into stored electrical energy is limited by the narrow spectral absorption range of standard silicon photovoltaics, as well as the sluggish charge insertion kinetics associated with conventional graphite anodes. To overcome these limitations, we present a system that uses nano-engineered alternatives to replace some of the conventional components at two key interface points in its operation. The harvesting module consists of perovskite nano-photovoltaic cells, designed with quantum dot (QD) absorbers and graphene transparent electrodes; this merger expands the spectrum absorption in QDs optics, facilitating the PCE reaching to 19.1% surpassing their maximum number predicted by silicon bandgap physics. The electricity produced will then be sent directly to a carbon-storage for ultra-capacity nano-enhanced storage device, which sees standard graphite anodes replaced by carbon nanotube-based electrodes and graphene supercapacitors. The unique attribute of these nanostructured electrodes is that their high surface-area-to-volume ratio leads to a significant increase in specific capacity and rapid charge buffering. Apply for a patent: New nano 3D thermal management created an active temperature control of the heat during energy transfer to FPGA cores allowing this resistive losses found in most commonuse configurations when charging. Consequently, the overall system efficiency is obtained as a product of multiplicative factors given by the photovoltaic generation efficiency, storage retention efficacy and enhanced charging process efficacy. Consequently, our architecture provides a direct, low-loss path from solar irradiance to the battery management system in the vehicle, facilitating rapid charge acceptance rates and minimizing energy dissipation. The main novelty is the coherent assembly of these nanomaterial-based building blocks into an integrated high-efficiency power network, which represents a revolutionary approach to clean electric mobility.
