Light Up The World solid state lighting project + (In times like these, scientists have been … In times like these, scientists have been able to utilize LED lights for more than just everyday bulb replacements. With the people working for the Light Up the World Foundation, solid state lighting is now helping thousands of people who don't have the proper means of getting artificial lighting. The foundation has been able to provide a simple technology using solid state lighting and LED lamps to under developed countries. Using a special design, the benefits of the lamps range from low maintenance to providing long lasting light. The reason this program is so beneficial is because having proper lighting will not only allow more work to be done to help families, but to also provide protection to communities that are potentially dangerous at night. The lighting used by the foundation is fairly simple to set up and does not need any form of electricity to work, but instead uses solar photovoltaic panels. The foundation will provide a kit that gets sent to different countries in need and can then be assembled there in the appropriate way. The best and most beneficial part of these systems is how positively they effect the environment. With low energy and very little pollution, they provide clean energy lighting that can last up to a year without replacement.can last up to a year without replacement.)

Solar Energy + (Increasing photovoltaic power output is wh … Increasing photovoltaic power output is what I work on. Solar energy produced by solar panels is a function of several factors: temperature, solar radiation density, and shade. The power output of PV increases when the solar radiation density on solar panels' surface is increased and decreases when solar panels' surfaces temperature and shade are increased. I started my experimental work on increasing solar arrays' efficiencies after I was done on my thesis for Net-Zero Energy for seven counties using solar, wind, and biomass https://etd.ohiolink.edu/!etd.send_file?accession=dayton1493070390195179&disposition=inline. Concentrating solar radiation on a PV surface is done by installing mirrors around the PV. the radiation density on the PV surface was increased depending on the number of the concentrators. Therefore, the PV power output increased by(15-25)% when using mirrors next to the PV. However, the PV's temperature was raised up when the solar radiation was increased. To recovery hast generated on the PV surface, I used a solar thermal system next to the back of the PV.lar thermal system next to the back of the PV.)
A Virtual Educational Exchange: A North-South Virtually-Shared Class on Sustainable Development + (Increasingly international competence is c … Increasingly international competence is considered and important skill to be acquired from an undergraduate education. Because international exchange presents a challenge to many students, there is a need to develop and implement alternative means for incorporating international and cross-cultural experiences into the undergraduate classroom. We report on the implementation of a semester-long, virtually-shared course offering between a U.S. and a Bolivian university. Since STEM (science, technology, engineering and mathematics) majors tend to be under-represented in study abroad programs, this class sought to provide a multidisciplinary experience that could be relevant to both hard and social science majors. Furthermore, the relevance and learning impact of this class was enhanced through the incorporation of a service-learning component in conjunction with a rural Bolivian partner organization. The results of this experience show that virtually-shared class-room experiences can successfully facilitate international experiences for undergraduate students.al experiences for undergraduate students.)

Economic Advantages of Dry-Etched Black Silicon in Passivated Emitter Rear Cell (PERC) Photovoltaic Manufacturing + (Industrial Czochralski silicon (Cz-Si) pho … Industrial Czochralski silicon (Cz-Si) photovoltaic (PV) efficiencies have routinely reached >20% with the passivated emitter rear cell (PERC) design. Nanostructuring silicon (black-Si) by dry-etching decreases surface reflectance, allows diamond saw wafering, enhances metal gettering, and may prevent power conversion efficiency degradation under light exposure. Black-Si allows a potential for >20% PERC cells using cheaper multicrystalline silicon (mc-Si) materials, although dry-etching is widely considered too expensive for industrial application. This study analyzes this economic potential by comparing costs of standard texturized Cz-Si and black mc-Si PERC cells. Manufacturing sequences are divided into steps, and costs per unit power are individually calculated for all different steps. Baseline costs for each step are calculated and a sensitivity analysis run for a theoretical 1 GW/year manufacturing plant, combining data from literature and industry. The results show an increase in the overall cell processing costs between 15.8% and 25.1% due to the combination of black-Si etching and passivation by double-sided atomic layer deposition. Despite this increase, the cost per unit power of the overall PERC cell drops by 10.8%. This is a significant cost saving and thus energy policies are reviewed to overcome challenges to accelerating deployment of black mc-Si PERC across the PV industry.ment of black mc-Si PERC across the PV industry.)

Modular Open-Source Design of Pyrolysis Reactor Monitoring and Control Electronics + (Industrial pilot projects often rely on pr … Industrial pilot projects often rely on proprietary and expensive electronic hardware to control and monitor experiments. This raises costs and retards innovation. Open-source hardware tools exist for implementing these processes individually; however, they are not easily integrated with other designs. The Broadly Reconfigurable and Expandable Automation Device (BREAD) is a framework that provides many open-source devices which can be connected to create more complex data acquisition and control systems. This article explores the feasibility of using BREAD plug-and-play open hardware to quickly design and test monitoring and control electronics for an industrial materials processing prototype pyrolysis reactor. Generally, pilot-scale pyrolysis plants are expensive custom designed systems. The plug-and-play prototype approach was first tested by connecting it to the pyrolysis reactor and ensuring that it can measure temperature and actuate heaters and a stirring motor. Next, a single circuit board system was created and tested using the designs from the BREAD prototype to reduce the number of microcontrollers required. Both open-source control systems were capable of reliably running the pyrolysis reactor continuously, achieving equivalent performance to a state-of-the-art commercial controller with a ten-fold reduction in the overall cost of control. Open-source, plug-and-play hardware provides a reliable avenue for researchers to quickly develop data acquisition and control electronics for industrial-scale experiments.ctronics for industrial-scale experiments.)

Modular Open Source Solar Photovoltaic-Powered DC Nanogrids with Efficient Energy Management System + (Initially the concept of a DC nanogrid was … Initially the concept of a DC nanogrid was focused on supplying power to individual homes. Techno-economic advances in photovoltaic (PV) technology have enabled solar PV stand-alone nanogrids to power individual devices using device-specific architectures. To reduce costs and increase accessibility for a wider range of people, a modular open-source system is needed to cover all applications at once. This article introduces a modular PV-powered nanogrid system, consisting of a do it yourself (DIY) PV system with batteries to allow for off-grid power. The resultant open-source modular DC nanogrid can deliver DC power to loads of different voltage levels, which is possible because of the efficient and parametric energy management system (EMS) that selects modes of operation for the grid based on DC bus voltage and state of charge of batteries. Simulation results verify the coordination between the EMS and the PV-battery system under varying PV power generation and load conditions. This EMS has potential to enable easy personalization of a vast area of applications and expand appropriate technology for isolated communities. A thorough stability analysis has been conducted, leading to the development of an LQR (Linear Quadratic Regulator) controller as a replacement for the conventional PI (Proportional - Integral) controllers for better transient stability of the system. better transient stability of the system.)
