Enhancing Bifacial Pv Efficiency With The Addition Of A Rear Side Reflector, Neila Watson
Enhancing Bifacial Pv Efficiency With The Addition Of A Rear Side Reflector, Neila Watson
Honors Theses
Bifacial photovoltaics are an expanding sector of solar electricity production, collecting solar energy on the front, back, and sides of the module. This increases the efficiency by around 10% to 30% over a typical mono facial cell, which only collects sunlight on the front. However, the performance of bifacial PV arrays depends on a variety of factors, including temperature, shadows, solar insolation, and set-up geometry. The geometry is affected by the tilt angle, the azimuth angle, the height from the ground to the panel, and the reflectance from the ground surface. The addition of a reflector, usually white in color …

A Molecular Dynamics Study Of The Laser Sintering Process And Subsequent Mechanical Properties Of Γ-Tial Nanoparticles, Eleanor Dickens
Honors Theses
Using molecular dynamics (MD) simulations, the laser sintering additive manufacturing process is investigated through the observation of γ-TiAl nanoparticles. This process is conducted using both uni-directional chain and stacking configurations. By mimicking the heating process and varying laser sintering parameters such as heating rater, sintering temperature, and particle orientation, the fusion behavior and resulting products are analyzed for both chain and stacking NP patterns. In of single chain cases, it is noticed that slower heating rates and higher melting temperatures yield larger neck growth between each individual particle and thus produce a more stable product. This leads to stronger mechanical …
Electromagnetically Propelled Garage Door, Connor Seifert
Electromagnetically Propelled Garage Door, Connor Seifert
Honors Theses
Garage door systems are loud and energy inefficient given their many contact points and need for continual maintenance. Most garage door systems use a loud, bulky electric motor to pull the garage door up and down using a chain. To reduce noise and energy loss due to friction from the electric motor and chain, electromagnetic forces used in Electromagnetic Suspension (EMS) trains were researched and adapted to a garage door system. The electromagnetically propelled garage door (EPGD) system was designed and validated using SOLIDWORKS and ANSYS simulation with significantly less contact points due to non-contact electromagnetic propulsion (EMP). The design …
