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 …

Design And Analysis Of A Process To Convert Methanol Into Dimethyl Ether, Elisa M. White
Honors Theses
A recent economic downturn led to the loss of a contract for a company that sells methanol. The company has two options to recover some of the profit lost from the contract termination. One option is to sell the excess methanol at the spot market price, and the second option is to implement a process to convert the excess methanol into dimethyl ether. This project investigated the implementation of a process to convert the methanol from the lost contract into dimethyl ether. The process was simulated in AVEVA Process Simulation to estimate the size of equipment needed. A toller provided …
