NEW ENGLAND SOUTHERN Developing a Novel DLC-Based Thermo-Photo-Betavoltaic Device for Remote Extensible Energy Conversion and Storage

Overview

This patent-pending project is a high-efficiency energy production, conversion, and storage device, capable of utilizing the low costs and superlative thermal, semiconductive, and electrical properties of diamond- like carbon (DLC). Various stacked DLC configurations were attempted, through physical development and simulation modeling. The thermo-photo-betavoltaic energy conversion and storage device would be compact, long-lasting, and energy-efficient, able to be used in various environments, including remote locations and extreme environments. It is necessary to produce a more extensible range of power output, with higher current densities, and operational capabilities at higher voltages, to serve the ever-increasing needs of data-intensive computing operations, especially those in remote conditions. High sp3/sp2 DLC is capable of superlative energy production using both heat and light, inherently possessing a wider bandgap potential (up to ~5eV). During use in field emission, applications have been shown to demonstrate superlative electron emission properties when exposed to a forward-bias voltage. A novel design is being proposed, utilizing waste graphite nuclear rods with DLC coatings to maximize the potential for energy output, while reducing the global supply of nuclear waste. Additional related designs are also proposed, utilizing thermophotovoltaics (converting thermal energy and photons into electrical energy), and betavoltaics (which generates electricity through the constant emission of beta particles), to lessen the dependence on greenhouse gases. Various stacked DLC configurations, primarily based on P-Njunction designs, were simulated, implemented, and tested, demonstrating a clear photoelectric and thermionic effect with up to ~100mV output tested, and a theoretical efficiency exceeding 25%, beyond today’s photovoltaic.
