Investigating the Durability and Reliability of PERC Solar Cells with Accelerated Weathering
Abstract - PERC (passivated emitter rear cell) monocrystalline silicon photovoltaic cells have higher efficiency than Al-BSF (aluminum back surface field) silicon photovoltaic cells, but these new PERC cell designs do not have well established...

Characterization of Gas-Liquid Interfaces in Passive Cyclonic Separators
Two-phase flows and their separation is an important research topic as many spacecraft require such functionality to remain operational. These systems are not required on earth due to the existence of buoyancy. Cyclonic...
Nicholas Barron with Jaoa Maia and Ed CanerLow Temperature Suspension of Shear Thickening non-Newtonian FluidsThere are a variety of useful applications in industry for shear thickening non-Newtonian fluids. For certain applications, maintaining shear thickening properties for long periods of time at temperatures below -25 Centigrade is desirable. In this...
Vipul Malik with Philip FengImproving the I-V characteristics of Molydinium DiSulfide transistors h-Boron NitrideMolybdenum disulfide (MoS2) transistors have attracted considerable attention. Molybdenum disulfide (MoS2) transistors on boron nitride (BN) substrates in particular show interesting I-V characteristics. Unfortunately these transistor devices currently exhibit undesirable I-V characteristics at low temperatures due to...
Matthew Krupcale with Philip FengNanoscale Membrane Structures for Radiation DetectionRadiation detectors are used in a wide range of environments from medical to nuclear and research facilities. The use of nanoscale membranes for radiation detection has largely been unexplored, despite having interesting optoelectronic properties. This project focuses on conducting a...

Photovoltaic Degradation Analysis and Two Diode Simulated Models
An understanding of the degradation process of photovoltaic modules during real world use is crucial to extending their lifetime and reliability. The degradation that occurs during normal use of a panel can be...
Christopher Miller with Philip FengPhysics and Instrumentation of Growing MoS2 CrystalsThis senior project is aimed at developing physical vapor deposition, transfer printing, and other related techniques for making ultra thin semiconducting membrane structures, which have potential to be engineered into transducers and sensors (e.g., gas sensors or single-particle detectors)...
