Solar District Cup Competition, Qi Jiang, Kristen A. Holman, Benjamin F. Aulenbab, Adi Alharbi, Chenge Liu
Sustainability Conference
The Solar District Cup is a two-semester design competition sponsored by the U.S. Dept. of Energy in which teams from across the nation compete to design the most efficient and cost effective solar plus storage system for a unique district case. The Embry Riddle team was tasked with designing such a system for New Mexico State University in Las Cruses, NM.

Solar energy is a renewable resource growing exponentially around the country over the past few decades. Solar energy works through the use of photo-voltaic cells, which work to convert energy from sunlight into electricity. This is done within solar panels, which are then connected to batteries for energy storage to use as needed. As production has increased over past decades, the cost for solar panel hardware and installment has thus fallen to meet consumer need. While most common implementations include solar panels attached to one’s home or solar panel ‘fields’ for charging entire towns, there has been a steady rise …

I noticed that the workers had the same itinerary when emptying trashcans, meanwhile trashcans needed urgently to be emptied. Traditionally, ETSU maintenance operate on daily routes to pick trash on designated time, regardless the level of the containers. This leads to overflown trashcan in busy areas or during rush hours in certain areas. This overflown trashcan result in an unclean environment for the community and an unpleasant look of our beautiful campus. The time, resources and labor invested in collecting the trash could be saved. Therefore, I decided to use the Internet of Things (IoT) to create a device that …
Novel Synthesis Of Cigs Nanoparticles For Scalable, Benign Inks For Solution Processed Solar Cells, Jacob Fields, Ryan Ellis, Rakesh Agrawal
Novel Synthesis Of Cigs Nanoparticles For Scalable, Benign Inks For Solution Processed Solar Cells, Jacob Fields, Ryan Ellis, Rakesh Agrawal
The Summer Undergraduate Research Fellowship (SURF) Symposium
One potential production route to high efficiency, low cost, photovoltaics (PVs) which was explored is Copper Indium Gallium Sulfide (CIGS) nanocrystal inks for solution processed PVs. A common CIGS nanocrystal ink synthesis utilizes ligands—molecules attached to the particle surface—for colloidal stability, size control, and shape control. It is desirable to devise a novel synthesis which will incorporate a ligand that allows suspensions in more benign solvents than current methods—a desirable characteristic for large scale production. In order to develop the aforementioned synthesis of CIGS nanoparticles, an optimization study of synthesis parameters was performed. Selection of an appropriate solvent, and sulfur …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Copper zinc tin sulfide (CZTS) is the abundant quaternary semiconducting compound which could be used to make solar thin film. Even though its efficiency is lower than the silicon based film, the cost of CZTS solar film will be lower compared to the current silicon based film. Therefore it is really worth to do research and make improvement on its efficiency. So far, the solar energy group already collected a great bunch of data, which could be employed to guide the future experiment. Hence, it is really necessary to build a database to arrange the information we got. Our project …

Photolithography In Fabrication Of Thin-Film Solar Cells, Yusheng Zhu, Rakesh Agrawal
The Summer Undergraduate Research Fellowship (SURF) Symposium
Solar energy has steadily increased its efficiency and cost-effectiveness throughout the past three decades and seems poised to compete with current primary energy (natural gas, oil, coal) as the need for alternative energy sources rises. One type of solar cell, thin-film cells, often relies on use of permanent photomasks in order to imprint a pattern onto the front metal contact. However, these machined metal masks are rigid and do not allow for different designs to be explored as current masks encounter difficulties in machining grids thin enough for optimization. Photolithography, traditionally used in the microfabrication field, provides a method in …

Natural structure with simultaneous negative permittivity and permeability has not been discovered yet. However, using specially-designed metal embedded in dielectric bodies can achieve a kind of artificial negative index. This periodic structure which is smaller than the guided wavelength is known as a metamaterial. However, recent designs of metamaterials have some disadvantages when they are used in the application of solar cell. The perfect absorption is only within a narrow band, and for most of the solar spectrum, the absorption is no more than 10%. Here, a new kind of absorber for the solar spectrum has been designed and analyzed, …
